Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical Obsolete technology relics that the Frank Sharp Private museum has accumulated over the years .
Premise: There are lots of vintage electrical and electronic items that have not survived well or even completely disappeared and forgotten.

Or are not being collected nowadays in proportion to their significance or prevalence in their heyday, this is bad and the main part of the death land. The heavy, ugly sarcophagus; models with few endearing qualities, devices that have some over-riding disadvantage to ownership such as heavy weight,toxicity or inflated value when dismantled, tend to be under-represented by all but the most comprehensive collections and museums. They get relegated to the bottom of the wants list, derided as 'more trouble than they are worth', or just forgotten entirely. As a result, I started to notice gaps in the current representation of the history of electronic and electrical technology to the interested member of the public.

Following this idea around a bit, convinced me that a collection of the peculiar alone could not hope to survive on its own merits, but a museum that gave equal display space to the popular and the unpopular, would bring things to the attention of the average person that he has previously passed by or been shielded from. It's a matter of culture. From this, the Obsolete Technology Tellye Web Museum concept developed and all my other things too. It's an open platform for all electrical Electronic TV technology to have its few, but NOT last, moments of fame in a working, hand-on environment. We'll never own Colossus or Faraday's first transformer, but I can show things that you can't see at the Science Museum, and let you play with things that the Smithsonian can't allow people to touch, because my remit is different.

There was a society once that was the polar opposite of our disposable, junk society. A whole nation was built on the idea of placing quality before quantity in all things. The goal was not “more and newer,” but “better and higher" .This attitude was reflected not only in the manufacturing of material goods, but also in the realms of art and architecture, as well as in the social fabric of everyday life. The goal was for each new cohort of children to stand on a higher level than the preceding cohort: they were to be healthier, stronger, more intelligent, and more vibrant in every way.

The society that prioritized human, social and material quality is a Winner. Truly, it is the high point of all Western civilization. Consequently, its defeat meant the defeat of civilization itself.

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

OLD, but ORIGINAL, Well made, Funny, Not remotely controlled............. and not Made in CHINA.

BANG & OLUFSEN BEOVISION 7702 YEAR 1984.







Designed by : David Lewis & Henning Moldenhawer
Finish : Rosewood, Teak, White


Replacing the Beovision 7700 in 1984, Beovision 7702 was a 22″ colour television which delivered a good 14 watts of sound through a 8cm woofer and 5cm tweeter in its log line loudspeaker system. The sound was mono. Teletext again was offered as an option as was the A/V interface.
It's sporting a PHILIPS 30AX CRT Tube.
The 30AX system, which Philips introduced in 1979, is an important landmark in the development of colour picture systems. With previous systems the assembly technician had to workthrough a large number of complicated setting-up procedures whenever he fitted a television picture tube with aset of coils for deflecting the electron beams. These procedures were necessary to ensure that the beams for the three colours would converge at thescreen for every deflection. They are no longer necessary with the 30AX system: for a given screen format any deflection unit can be combined  with any tube to form a single 'dynamically convergent' unit. A colour-television receiver can thus be assembled from its components almost as easily as a monochrome receiver. The colour picture tube of the PHILIPS 30AX system displays a noticeably sharper picture over the entire screen surface. This will be particularly noticeable when data transmissions such as Viewdata and Teletext are displayed. This has been achieved by a reduction in the size of the beam spot by about 30%. Absence of coma and the retention of the 36.5 mm neck diameter have both contributed to increased picture sharpness. Coma has been eliminated by means of corrective field shapers embedded in the deflection coils which are sectionally wound saddle types. The new deflection unit has no rear flanges. enabling uniform self-convergence to be obtained for all screen sizes. without special corrections, adjustments, or tolerance compensations. Horizontal raster distortion is reduced and no vertical correction is required. One of the inventions in 30AX is an internal magnetic correction system which obviates static convergence and colour purity errors. This enables the usual multiple unit to be dispensed with. together with the need for its adjustment !  New techniques have been employed to achieve close tolerance construction of the glass envelope. In addition, the 30AX picture tube incorporates two features whereby it can be accurately adjusted during the last stages of manufacture. One is the internal magnetic correction system. The other is an array of bosses on the cone that establish a precise reference for the axial purity positioning of the deflection unit on the tube axis and for raster orientation. During its manufacture, each deflection unit is individually adjusted for optimum convergence. The coil carrier also incorporates reference bosses that co-operate with those on the cone of the tube. ' Since every picture tube and every deflection unit is individually pre-aligned, any deflection unit automatically matches with any picture tube of the appropriate size. The deflection unit has only to be pushed onto the neck of the tube unit it seats. Once the reference bosses are engaged, the combination is accurately aligned and requires no adjustment for convergence, colour purity or raster orientation. With no multiple unit and a flangeless deflection unit, there is more space in the receiver cabinet. Higher deflection sensitivity means that less current is consumed, and consequently less heat is produced. This increases the reliability of the TV receiver again. 30AX means simple assembly. Any picture tube is compatible with any deflection unit of the appropriate size and is automatically self-aligning as well as being self-convergent.

The well-known 20AX features of HI-Bri, Soft-Flash and Quick-vision are maintained in the new 30AX systern.  In their work on the design of deflection coils in the last few years the developers have expanded  the magnetic deflectionfields into 'multipoles', This approach has improved the understanding  of the relations between coil and field and between field and deflection to such an extent that  designing deflection units is now more like playing a difficult but fascinating game of chess than  carrying out the obscure computing procedure once necessary.

It was one of the threesome: the Beovision 5502 had a 20″ screen, Beovision 7702 had a 22″ screen and the largest, the Beovision 8802 had a 26″ screen size.

Only superficially different from its predecessor, electronic tuning was installed for the first time which allowed the user to store up to 32 channels in its electronic memory.

Therefore, Bang &; Olufsen equipped all the luxury Beovision models with an advanced digital tuner that had the capacity for receiving 100 UHF channels, 32 of which could be stored in the set's microcomputer memory for instant recall at the touch of a button.

The real boon for most viewers is that you could locate, store and recall any of these stations without leaving your armchair. All you had to do was touch a key on the Beovision Video terminal. So although B&O gave its "future-safe" luxury TV range more micro-electronics, more features and more connection possibilities than ever before, they made, at the same time, all the complex technology even more accessible - instantly. To borrow a phrase from the computer industry, Bang & Olufsen's '02-Series' TVs were "user-friendly".

Beovisions 5502, 7702, 8802 and 9002 all shared the same advanced chassis design and offered the same user-benefits. They were true "luxury" sets because many 'extras' offered by other companies, were given as standard by Bang & Olufsen.

The Beovision Video Terminal supplied with Beovisions 5502, 7702, 8802 and 9002 offered a plethora of operational benefits. In addition there was also an advanced 'tune and store' function that allowed you to operate the automatic tuning system from the comfort of your chair.

One touch of the 'tune' button started the digital tuner scanning the wavelengths of the UHF band. When it found a station, it stopped - giving you the opportunity to either reject or accept it. If it was an unsatisfactory reception from a distant transmitter (or simply a station you don't like!), you just pressed 'tune' again to continue the search. When you found a station you enjoy, on a channel giving a good, clear reception, you could instruct the set's microcomputer to remember that transmission frequency by pressing 'store' followed by your own choice of pre-set programme number (e.g. for BBC2 you might designate pre-set number 2). Thereafter, whenever you wanted to watch BBC2, you simply touch button '2' on your remote Terminal.

Up to 32 different TV stations could be located and stored in this way, so your Beovision really is 'future-safe' because it has plenty of spare capacity to accommodate new programme sources as and when they come 'on stream'.

The latest type of Beovision Video Terminal also had a button marked 'sound'. This was only effective with Bang & Olufsen stereo TVs - Beovision 7802 and Beovision 8902.

Beovision 5502 had a 50cm screen and measured 62cm wide, 40cm high (71.5cm including stand) and 39cm deep.

Beovision 7702 had a 22" screen. Dimensions were 67.5cm wide, 43.5cm high ( 76cm including stand) and 41.5cm deep.

Beovision 8802 had a 26" screen and measured 77cm wide, 49cm high (80cm including stand) and 45.5cm deep.

All three models had slim cabinets finished in a choice of natural teak or rosewood. White finish was available to special order.
Revamped slightly in its three year life, it became an excellent, reliable set; many examples are still in use today representing this high point in Bang & Olufsen engineering.
With stereo reception becoming more and more available in the late 1980s, Beovision 7702 was to become the very last monophonic 22″ TV produced by the company.
It was replaced by the stereo Beovision 7802 model.

Bang & Olufsen Holding A/S (B&O) is a leading consumer electronics firm, manufacturing a complete line of technologically sophisticated, sleekly-designed hi-fis, speakers, televisions and telephones. The company sells its products in 40 countries through a network of more than 2.000 stores that are partly owned by the company. Renowned for its attention to design and leading-edge technology, the company represents a singular force in the multibillion-dollar consumer electronics industry.

Peter Bang and Svend Olufsen grew up in era of swift technological innovation. Both were born around the time Guglielmo Marconi made his 1901 transmission of long-wave radio signals across the Atlantic Ocean in a historic achievement that set the stage both youths’ experiments with radios. At the age of ten Peter Bang read about the world’s first live radio transmission and Enrico Caruso’s performance at New York’s Metropolitan Opera in 1910. Soon after, he began his first experiments with radio, eventually leading him to pursue an engineering degree at the Electrotechnical School in Århus, Denmark. After earning his degree in 1924, Peter Bang moved to the United States, where the flourishing radio industry had 600 commercial broadcasting stations and so presented fertile ground for exploring his interests. In the USA Peter Bang worked at a service station and at a radio manufacturing plant, but he soon felt entrepreneurial urges again. After six months he returned to Denmark, intent on starting his own business.

Back in Denmark, Svend Olufsen was busy building his own radio. Olufsen also liked to experiment with electricity and chemistry and had attended the Electrotechnical School at the same time as Bang, also earning an engineering degree. Olufsen began his radio experiments at his family’s Quistrup estate, occupying a room in the attic where he started building a mains receiver, a radio that required neither accumulators nor the batteries needed to recharge them. While he was away at boarding school and later at the Electrotechnical School, Bang had written frequently to his father asking for money to pay for more batteries. Bang’s mains receiver would be the prototype upon which Olufsen’s experiments would be based.

At Quistrup, Olufsen’s mains receiver was half finished when Bang returned from the United States. Olufsen needed help, and his former classmate was uniquely qualified to provide it. Bang left Copenhagen and traveled to the countryside in the west to the Olufsens’ Quistrup. There, in the attic that would serve as B&O’s first laboratory, Bang and Olufsen worked together on the mains receiver, a nest of thick copper wire and insulated cables that stretched from one side of the room to the other. The pair used the money Olufsen’s mother received for selling the farm’s eggs to finance their endeavor. Before long, Bang achieved his entrepreneurial dreams. In 1925, Bang and Olufsen, with the backing of their fathers, formed a limited company funded with DKK 10,000.


After traveling to Copenhagen, where the necessary papers were drawn up, naming Bang’s father, Camillo Cavour Bang, as B&O’s first chairman of the board, the two radio aficionados returned to Quistrup. Bang moved into the attic, putting his bed in the same room as the mains receiver. Bang and Olufsen hired the cowman’s daughter as the company’s sole employee, whose first task each morning was to wake up Bang 15 minutes before the company’s day officially began. The company’s first product was the B&O Eliminator, a device–an aggregate–that connected a battery receiver to the mains to produce noise-free current.

B&O grew quickly. By 1927, the activities in the attic had spread throughout the estate and spilled onto the lawns, where B&O Eliminators were assembled by a staff of 30. Quistrup could no longer accommodate the growth of the company’s payroll and the sprawl of the manufacturing operations, forcing Bang and Olufsen to establish a new site for the company’s headquarters. Their fathers, who together owned 20 percent of the company, remained unconvinced that radio would last, so they stipulated that the new factory be designed as a school building in case radio proved a fleeting fancy. In 1927, B&O moved into its new factory, and the company soon began development of a new radio.

By 1929, the company had completed the design of its breakthrough radio, the Five Lamper and its peripheral “Type D” loudspeaker. Powered from the mains, the Five Lamper only required connection to an electrical outlet for operation. It was the company’s first signal success, embodying the two characteristics that would define B&O’s success in the decades to follow: style and technology. The Five Lamper was a technological marvel, displaying what would become a signature trait of B&O’s products. The Five Lamper was also the first radio encased in a walnut cabinet, exuding elegance in design that drew its inspiration from the Danish furniture industry. For B&O, the combination of style and technology would prove to be a potent formula for success, becoming the foundation upon which all of its subsequent products were based.

The Five Lamper established B&O in the Danish market, securing a leading and lasting position for the West Jutland company, far removed from the hub of activity in Copenhagen. Strong sales and a sleek design at a time when radios were clunky and cumbersome set B&O apart, establishing a reputation that the company would solidify during the 1930s. During that decade, B&O introduced new products, including a radio gramophone in 1930 and several new radio models (Radio 5 RGF, Hyperbo 5 RGF, and Beolit 39). These products notwithstanding, the years preceding World War II were most notable for less tangible results. The 1930s saw B&O strengthen its image as a design-oriented, technology-driven company. It was a company that proclaimed itself as “The Danish Hallmark of Quality” registered as the company’s slogan in 1931, and a company that bore a “pregnant B” inspired by the Bauhaus school of design as part of its corporate logo, trademarked in 1932.

The outbreak of World War II cast a pall over the future of B&O just as the company had taken a firm hold on the Danish market. Denmark was largely defenseless against the onrush of the German Blitzkrieg, and within seven months of the war’s start, the country was occupied by German troops. Not surprisingly, raw materials became hard to come by, particularly radio tubes, but Bang and Olufsen had anticipated the war’s arrival and had begun increasing their stock of essential parts as far back as 1935. Consequently, B&O was able to retain its full workforce during the first few years of the war, a rare feat for Danish manufacturing companies. Ultimately, however, B&O paid a price for its resilience and, specifically, for its resistance. In January 1945, the Germans bombed B&O’s factory, targeting the building because the company had refused to collaborate and because a number of B&O employees were suspected Danish Resistance members. Construction of a new factory began the day after the bombing and was completed in early 1946, but it took another year before full production was resumed.

As B&O recovered from the turmoil of the 1940s, it enjoyed a brief respite before another portentous event clouded the company’s future. After introducing electric shavers into the market in 1946 - a diversification spawned from the scarcity of raw materials during World War II - B&O started manufacturing televisions and tape recorders, fleshing out its product line as it honed its skills in design. Beginning in the 1950s, the company began soliciting the help of Denmark’s renowned architects and designers, drawing from the pool of talent that had made the Danish furniture industry an influential force in design. The effect of the company’s collaboration with the country’s leading designers became evident during the latter half of the 1950s, as B&O radios, televisions and tape recorders earned high praise for their aesthetic appeal. At the same time, by the end of the 1950s, the company’s prospects for survival appeared grim. A little more than a decade after rebuilding its factory, the company again faced the considerable might of the Germans, a face-off that few industry observers believed B&O could withstand.

B&O’s concerns stemmed from the 1957 Treaty of Rome, which spawned the European Economic Community. Tariffs, duties, and customs were relaxed between member countries, leading to the consensus that the Danish radio industry, comprising approximately 20 small companies, would be subsumed by the superior strength of the much larger German manufacturers. The looming threat of much stiffer competition forced B&O to rethink its strategy, prompting the company to leverage its esteemed design expertise and its experience selling semiprofessional, high-fidelity equipment to the United States as the basis for its new approach. The company decided to sacrifice its leading market position in Denmark in order to concentrate on the much larger European market, forsaking dominance in a small market for a small share of a bigger market. In accordance with the new business focus, the company began to develop an entirely new line of stereo products that catered to the high end of the market, an approach evident in the slogan adopted during the 1960s: “B&O - for those who discuss taste and quality before price”.

B&O’s efforts to penetrate the European market bore fruit with the introduction of the Beomaster 900. The Beomaster 900 did to Europe what the Five Lamper had done to Denmark 30 years earlier: the transistorised radio became a success throughout Europe, and despite the company’s fears, its share of the Danish market did not diminish. The Treaty of Rome had forced many of the Danish manufacturers out of business, leaving B&O in a position to strengthen its domestic lead. By the time Beomaster 900 was introduced, B&O was ready to secure a presence in the then-developing market for high-fidelity systems. The company wanted to establish the standard by which all stereo systems would measured, an ideal that was realised with the Beolab 5000 series. Featuring a sensitive tuner, a powerful amplifier, and linear controls instead of knobs, the Beolab 5000 became B&O’s second European success, spawning more affordable versions, Beomaster 1200 and Beomaster 3000.

Having established itself as a genuine contender in the vast European market, B&O spent the late 1960s restructuring its operations to conform to its new market orientation. The company established subsidiaries that replaced a network of agents that had previously carried out the international distribution. The reorganization included the formation of Bomark in 1970, which created an international marketing department responsible for coordinating all of the company’s marketing activities. Previously, the company had taken whatever advertising it had created for the Danish market and used it to support its foreign marketing efforts, changing it only slightly to reflect cultural and market differences. The new system regarded the Danish market as only one of many markets, driving the company’s evolution toward becoming a multinational concern. B&O marketing adopted the company’s new perspective, as advertising campaigns became specifically tailored for the nuances of individual markets amid divergent cultures.

After the success of Beolab 5000, B&O next prodded its engineers and designers to develop a complete array of stereo components. The first product to make its debut was Beogram 4000, a turntable introduced in 1972 featuring a tangential arm that reproduced a recording in the same way in which it had been made. The record player was designed to target a different, much larger market segment, music lovers rather than the more exclusive retinue of technology-focused customers. Advanced technology, always an integral aspect of B&O’s products, was not forsaken, but hidden beneath the surface, as the company’s products earned a new distinction of exterior simplicity. This quality was first evident in Beomaster 1900, a system introduced in 1975 that market a turning point in the evolution of the B&O product line. For the next 20 years, Beomaster 1900 would be the company’s best-selling product.


Problems in the 1980s resolved in the 1990s

This success notwithstanding, the 1980s proved to be a difficult decade for B&O, as the company struggled to beat back fierce competition from its Asian rivals. Although external pressures played their part, the company also fell victim to internal problems, problems of its own making that B&O’s management was slow to acknowledge. The company’s distributors lost faith in the B&O product line, and revenues began to slip. Initially, B&O tried to arrest its slide by narrowing its market focus on its wealthiest customers, but in the process the company’s products lost some of their integrity, as substance was sacrificed for style. The company also tried to restore loyalty within its distributor ranks by staging seasonal product launches in exotic locations, but the effort failed. B&O’s fundamental problem had to do with the decentralization that followed the company’s full-fledged foray into international markets. The subsidiaries, by the 1980s, had become separate fiefdoms, which led to overspending, high costs, and superfluous bureaucratization. At the same time, the company had lost the ability to react nimbly to changing market conditions.

Before the end of the decade, B&O became a cash-strapped enterprise. The need for capital led to a strategic alliance with Koninklijke Philips Electronics N.V., the Dutch consumer electronics conglomerate, but the capital gained from the investment was soon drained. Rudderless and ailing financially, B&O entered the 1990s in crisis mode.

Salvation arrived in May 1991, when B&O’s board of directors installed a new management team, led by Anders Knutsen. Knutsen’s first task was to cut costs, an objective fulfilled by laying off employees, streamlining operations, and paring away excess layers of management. Knutsen also implemented a new strategic plan known as “Break Point 1993″ which addressed the problems born of the company’s earlier decentralization. Knutsen reintroduced centralized management and made the company more responsive to the demands of its customers. Stocks of finished products and parts were removed from many of B&O’s subsidiaries, as Knutsen transformed B&O from a company geared for mass production into an enterprise organized to fulfill customers’ orders. The changes sparked a turnaround, refreshing the spirit and resharpening the focus that had predicated B&O’s success.

At the end of the 1990s, B&O approached its 75th anniversary as a unique competitor in the consumer electronics industry. The company’s attention to design and its long record of technological advancements remained the qualities that set the B&O name apart. With sales nearing the half-billion-dollar mark by the century’s end, B&O promised to figure as a prominent force in the years ahead, as a new generation of high-technology stereos, speakers, and televisions and telephones continued the legacy established by Peter Bang and Svend Olufsen.

Resisting the tide of post-modernity may be difficult, but I will attempt it anyway.
