Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical 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.

Every CRT Television saved let revive knowledge, thoughts, moments of the past life which will never return again.........

Many contemporary "televisions" (more correctly named as displays) would not have this level of staying power, many would ware out or require major services within just five years or less and of course, there is that perennial bug bear of planned obsolescence where components are deliberately designed to fail and, or manufactured with limited edition specificities..... and without considering........picture......sound........quality........

..............The bitterness of poor quality is remembered long after the sweetness of todays funny gadgets low price has faded from memory........ . . . . . .....
Don't forget the past, the end of the world is upon us! Pretty soon it will all turn to dust!

Have big FUN ! !

SIEMENS ELETTRA TV2459 YEAR 1969.



































The SIEMENS ELETTRA TV2459 is a 24 inches B/W television entirely based on tubes and furthermore has a chassis with "in air" wired circuitry.

Other brands were already using PCB or at least partly using PCB.

The set has 4 programs with push button and manual potentiometric search tuning.




The B/W Tubes Television set was powered with a External Voltage stabiliser unit for Television (portable metal box) which relates to voltage regulators of the type employed to supply alternating current and a constant voltage to a load circuit from a source in which the line voltage varies. Such regulators are frequently provided employing saturable core reactors and condensers connected in circuit...  in such manner as to provide a plurality of variable voltage vectors which vary in different senses, as the line voltage varies, but which add vectorially in such manner that the
voltage stabilization
is automatically effected by the provision of an inductive pilot control device which is adapted to provide two excitation supply voltages for producing excitation or satuation of two magnetic circuits of a reversible booster transformer unit or units and diversion of flux from one magnetic circuit to the other, the booster unit being energized by primary windings from the A. C. supplysystem and being provided with a secondary winding or windings connected between the supply system and the corresponding inain or distribution circuit and in series therewith, through which a corrective boost voltage is
introduced into the circuit under the influence of the pilot control device, of an amount equal to that of the supply voltage fluctuation which initiated it and appropriate in polarity and direction for restoring the voltage to normal value and providing automatic stabilization of the circuit voltage against supply voltages which fluctuate above and below normal value.



Their vector sum remains substantially constant upon variations in line voltage, for providing automatic voltage stabilization of single or multiphase A. C. circuits where the supply voltage and frequency are subject to variation above and below normal value and where the load is subject to variation between normal limits.
The pilot control device which may be employed singly or may comprise three units or their equivalent when applied to multiphase supply systems comprises a pair of closed magnetic circuits or cores constructed of strip wound magnetic material or stacked laminations, the two
circuits forming a pair being constructed of materials possessing dis~similar magnetic characteristics when jointly energized by identical windings in series or by a collective primary winding, the said magnetic circuits being suitably proportioned to provide equal fluxes when energized at normal voltage.

The pilot control device is provided with a main and an auxiliary secondary winding or group of windings, the main secondary winding or windings being adapted to provide a voltage representing the difference in the fluxes of the two circuits to which it is jointly associated, while
the auxiliary secondary winding embraces only one circuit, preferably that subject to the least amount of flux variation. Either of the windings consists of two equal sections or in effect a double winding with a center tapping to which one end of the single winding is connected.

The voltage in the single secondary winding of the pilot device becomes directionally additive to that in one half of the tapped secondary winding a nd substractive in respect to that in the other half. When the supply voltage is normal the voltage provided by the single secondary winding is zero, since there is no difference of flux in the two magnetic circuits, and the two excitation voltages
produced in the halves of the other secondary winding are equal and when connected to the two excitation windings of the booster units, do not produce any diversion of flux between the two circuits or sets of circuits in the magnetic system of the booster transformer unit become equal, and since the series winding on the booster unit is arranged to provide a voltage due to the difference of
the fluxes in its two magnetic circuits or sets of magnetic circuits, no corrective voltage is introduced into the main circuit by the booster. If, however, the supply voltage varies from normal the pilot control device provides a voltage across the one secondary winding due to the difference in the fluxes of the two dis-similar magnetic circuits of which it is comprised, which voltage is combined with thosc in the halves of the other secondary winding to provide two excitation voltages which vary complementarily to each other as the supply voltage fluotuates, and cause a transference of flux between the two
circuits or groups of circuits in the booster unit and automatically provide a corrective boost voltage in the main circuit in which the series winding of the booster transformer is included of a value equal to that of the variation in supply voltage which initiated it.
The pilot device may be arranged in various ways, forboth single phase and multiphase operation, as exemplified by the constructions hereinafter more fully described.Similarly, numerous arrangements of the booster transformer unit are possible, some of which are hereinafter described in detail. The booster transformer unit embodies thc principles of the inductive devices described in my co-pending Application No. 411,189, filed February 18, 1954.

As an alternative to the provision of an auxiliary secondary winding on the pilot control device this may be
replaced by an independent or external source of supply,which may be either subject to or independent of supply voltage variation, provided such supply may be arranged with a center tapping if required.

Feed-back arrangements may be employed for providing compensation against voltage drop due to the effects of load in various ways. These are preferably providedon the booster transformer unit and may comprise a current transformer in one or more lines of the main circuit,
the secondary output of the transformer being rectified and arranged to energize an additional excitation winding on the booster transformer unit which in clfect increases the amount of the corrective boost voltage as the load increases.

Today, Siemens, with its world class solutions plays a key role in India’s quest for developing modern infrastructure.

With effect from March 14, 2011, Siemens Healthcare Diagnostics Ltd. (SHDL) amalgamated with Siemens Ltd. and stands dissolved. Siemens Ltd. has issued and allotted 3,134,700 Equity Shares of ` 2 each fully paid–up to the shareholders of erstwhile SHDL on 24th March, 2011. The entire business and undertaking of the company now gets transferred to and in the name of Siemens Ltd. In 2010 Siemens Home Appliances launched a washing machine model which saves energy.

In May 2011, Siemens received the Certificate of Registration from the Reserve Bank of India (RBI) to operate a non banking finance company for its financial services business in India, Siemens Financial Services Private Limited (SFSPL). SFSPL will focus on developing an asset financing business by offering products such as loans, leasing and other finance products as permitted by the RBI to Siemens customers in India in the Industry, Energy and Healthcare sectors, as well as pursuing opportunities in other third party markets.

In August 2011, the Healthcare Sector of Siemens Ltd. installed five state of the art medical technologies at Kovai Medical Center & Hospital in Coimbatore, raising quality and efficiency of healthcare availability in this city. Making its presence for the first time in Tamil Nadu, these technologies allow highly accurate and early diagnosis of all kinds of ailments, thus aiding precise treatment.

Founder generation

Siemens & Halske was founded by Werner von Siemens on 12 October 1847. Based on the telegraph, his invention used a needle to point to the sequence of letters, instead of using Morse code. The company, then called Telegraphen-Bauanstalt von Siemens & Halske, opened its first workshop on October 12.
In 1848, the company built the first long-distance telegraph line in Europe; 500 km from Berlin to Frankfurt am Main. In 1850 the founder's younger brother, Carl Wilhelm Siemens started to represent the company in London. In the 1850s, the company was involved in building long distance telegraph networks in Russia. In 1855, a company branch headed by another brother, Carl Heinrich von Siemens, opened in St Petersburg, Russia. In 1867, Siemens completed the monumental Indo-European (Calcutta to London) telegraph line.
In 1881, a Siemens AC Alternator driven by a watermill was used to power the world's first electric street lighting in the town of Godalming, United Kingdom. The company continued to grow and diversified into electric trains and light bulbs. In 1890, the founder retired and left the company to his brother Carl and sons Arnold and Wilhelm.

Turn of the century

Siemens & Halske (S&H) was incorporated in 1897, and then merged parts of its activities with Schuckert &; Co., Nuremberg in 1903 to become Siemens-Schuckert.
In 1907 Siemens (Siemens & Halske and Siemens-Schuckert) had 34,324 employees and was the seventh-largest company in the German empire by number of employees. (see List of German companies by employees in 1907)
In 1919, S&H and two other companies jointly formed the Osram lightbulb company. A Japanese subsidiary was established in 1923.
During the 1920s and 1930s, S&H started to manufacture radios, television sets, and electron microscopes.
In 1932, Reiniger, Gebbert & Schall (Erlangen), Phönix AG (Rudolstadt) and Siemens-Reiniger-Veifa mbH (Berlin) merged to form the Siemens-Reiniger-Werke AG (SRW), the third of the so-called parent companies that merged in 1966 to form the present-day Siemens AG.
In the 1930s Siemens constructed the Ardnacrusha Hydro Power station on the River ShannonIrish Free State, and it was a world first for its design. The company is remembered for its desire to raise the wages of its under-paid workers only to be overruled by the Cumann na nGaedheal government. in the then


World War II era

Preceding World War II, Siemens was involved in funding the rise of the Nazi Party and the secret rearmament of Germany. During the second World War, Siemens supported the Hitlerconcentration camps to build electric switches for military uses. In one example, almost 100,000 men and women from Auschwitz worked in a Siemens factory inside the camp, supplying the electricity to the camp. regime, contributed to the war effort and participated in the "Nazification" of the economy. Siemens had many factories in and around notorious
Siemens businessman and Nazi Party member John Rabe is credited with saving hundreds of thousands of Chinese lives during the Nanking Massacre. He later toured Germany lecturing on the atrocities committed in Nanking.
In the 1950s and from their new base in Bavaria, S;H started to manufacture computers, semiconductor devices, washing machines, and pacemakers.
In 1966, Siemens &;; Halske (S&H, founded in 1847), Siemens-Schuckertwerke (SSW, founded in 1903) and Siemens-Reiniger-Werke (SRW, founded in 1932) merged to form Siemens AG.
In 1969, Siemens formed Kraftwerk Union with AEG by pooling their nuclear power businesses.
The company's first digital telephone exchange was produced in 1980. In 1988 Siemens and GECPlessey. Plessey's holdings were split, and Siemens took over the avionics, radar and traffic control businesses — as Siemens Plessey. acquired the UK defence and technology company
In 1985 Siemens bought Allis-Chalmers' interest in the partnership company Siemens-Allis (formed 1978) which supplied electrical control equipment. It was incorporated into Siemens' Energy and Automation division.
In 1987, Siemens reintegrated Kraftwerk Union, the unit overseeing nuclear power business.
In 1991, Siemens acquired Nixdorf Computer AG and renamed it Siemens Nixdorf Informationssysteme AG, in order to produce personal computers.
In October 1991, Siemens acquired the Industrial Systems Division of Texas Instruments, Inc, based in Johnson City, Tennessee. This division was organized as Siemens Industrial Automation, Inc., and was later absorbed by Siemens Energy and Automation, Inc.
In 1997 Siemens agreed to sell the defence arm of Siemens Plessey to British Aerospace (BAe) and a German aerospace company, DaimlerChrysler Aerospace. BAe and DASA acquired the British and German divisions of the operation respectively.
In 1999, Siemens' semiconductor operations were spun off into a new company known as Infineon Technologies. Also, Siemens Nixdorf Informationssysteme AG formed part of Fujitsu Siemens Computers AG in that year. The retail banking technology group became Wincor Nixdorf.

In 2000 Shared Medical Systems Corporation was acquired by the Siemens' Medical Engineering Group, eventually becoming part of Siemens Medical Solutions.
Also in 2000 Atecs-Mannesman was acquired by Siemens, The sale was finalised in April 2001 with 50% of the shares acquired, acquisition, Mannesmann VDO AG merged into Siemens Automotive forming Siemens VDO Automotive AG, Atecs Mannesmann Dematic SystemsMannesmann Demag Delaval merged into the Power Generation division of Siemens AG Other parts of the company were acquired by Robert Bosch GmbH at the same time. merged into Siemens Production and Logistics forming Siemens Dematic AG,
