REX (Zanussi) 20RM302 "TAHITI" YEAR 1982.

The REX  (Zanussi) 20RM302 "TAHITI" is A 20 Inches color television with remote and 29 programs and for first time a pll frequency synthesizer channel search featured with a microcomputer.A microcomputer control system is described for effecting channel tuning and function selection in a television receiver. The system will respond to commands entered by a set of controls at the television receiver or to remote control commands received at the television receiver. A channel number display is also provided whereby the channel number of a station currently tuned is displayed. A microprocessor within the system is programmed to validate control information received from an operator either by remotely generated commands or by controls located on the television receiver. Operator supplied information is processed and implemented by the microprocessor control system to effect control over the television receiver.
Microprocessor technology has recently provided circuit designers with a new basic design component. The microprocessor is capable of duplicating many functions heretofore realized with the use of large scale computer systems. The microprocessors have the advantage of being small, low power consumption devices capable of being programmed with instructions for executing mathematical algorithms on data supplied to the microprocessor. The microprocessor, when properly programmed, will execute a set of instructions providing output data during execution which may be used to control a process or apparatus.
The control of television receivers has heretofore required separate circuits for effecting channel selection, function selection and level setting, and remote control. With the microprocessor it has become possible to control these performance aspects with a single preprogrammed microprocessor and suitable input/output circuits. Data indicating the selection of a new channel to be tuned or a function to be controlled by an operator of the television receiver may be supplied to the input port of the microprocessor. This data may be supplied from a set of hand controls or a transducer for detecting remotely generated commands. Remote control systems presently incorporated in many television receivers provide operation of a television receiver by transmitting information bearing ultrasonic sound waves or infrared light waves to the television receiver. These waves when received at the television receiver are decoded into an electrical signal for effecting the change in channel tuning or function level. The microprocessor has the capability of validating this electrical signal and performing all decoding pursuant to preprogrammed instructions. These instructions, when executed by the microprocessor, generate a digital signal for effecting the desired channel change or function level change.


- Was first ZANUSSI Color tv featuring the PHILIPS TDA3560 Complete Pal Decoder with integrated circuit providing the color decoder of a television receiver set and in particular for a multistandard decoder for NTSC, PAL and SECAM (Here only PAL) .
Conventionally employed external components used for synchronizing and amplitude calibration are replaced by circuits forming part of an integrated circuit, which automatically adjust for the desired operational mode such as NTSC, PAL or SECAM in each case. This system saves previously required external components such as trimming resistors, potentiometers or quartz crystals.
It combines all functions required for the identification and demodulation of PAL signals.
Furthermore it contains a luminance amplifier, an RGB-matrix and amplifier. These
amplifiers supply output signals up to 5 V peak-to-peak (picture information) enabling direct drive of the discrete output stages.

- This models series was first ZANUSSI set using a Microcomputer (SGS) for Tuning and control functions.The use of indirect frequency synthesis , microcomputer-controlled tuning system, in television tuning systems was increasing because of the inherent advantages of this frequency tuning approach.

The indirect frequency synthesis tuning system utilizes a phase lock loop (PLL) that employs the local oscillator (LO, of the tuner for its voltage controlled oscillator (VCO). A stable, accurate reference signal is generated by a crystal oscillator and compared to the output of the LO that has been divided down in frequency in the PLL. By counting down from the LO which provides one input to the phase comparator, the PLL causes the signal thus produced to be exactly the same frequency as the reference signal which provides the other input to the phase comparator. The two signals will be slightly out of phase due to the static phase error of the PLL. With the PLL forcing both of the inputs to the phase comparator to be equal in frequency, a change in the division ratio between the LO and the phase comparator will result in a different LO frequency. It's a color television with PLL frequency synthesized tuning system, a television tuning system employs a frequency synthesizer system for establishing the tuning of the receiver, featured with a Microcomputer driven synthesis system.

The system employed in the tv permits utilization of a frequency synthesizer tuning system which correctly tunes to a desired television station or channel even if the transmitted signals from that station are not precisely maintained at the proper frequencies even in combination of a fine tuning adjustable by the user.

Accordingly, it is an object of this invention to provide an improved tuning system for a television receiver.
It is an additional object of this invention to provide an improved frequency synthesizer tuning system for a television receiver.

It has a Transistorized horizontal deflection circuits  made up of a horizontal switching or output transistor, a diode, one or more capacitors and a deflection winding. The output transistor, operating as a switch, is driven by a horizontal rate square wave signal and conducts during a portion of the horizontal trace interval. A diode, connected in parallel with the transistor, conducts during the remainder of the trace interval. A retrace capacitor and the deflection yoke winding are coupled in parallel across the transistor-diode combination. Energy is transferred into and out of the deflection winding via the diode and output transistor during the trace interval and via the retrace capacitor during the retrace interval.
In some television receivers, the collector of the horizontal output transistor is coupled to the B+ power supply through the primary windings of the high voltage transformer.

The New chassis BS500 Was very reliable with few issues mainly in EHT external bleeder faults.


Zanussi was an Italian producer of home appliances that in 1984 was bought by Electrolux . Zanussi is a leading brand for domestic kitchen appliances in Europe. Products have been exported from Italy since 1946.

The Zanussi Company began as the small workshop of Antonio Zanussi in 1916. The enterprising 26-year-old son of a blacksmith in Pordenone in Northeastern Italy began the business by making home stoves and wood-burning ovens.
After his father death in 1946 “Lino Zanussi” became the President of the company.
In the early 1970s Zanussi sold a lot in the UK and for some time after under the “Zoppas” brand, name which had been acquired, making Zanussi the first largest Italian appliance maker. They also produced washing machines Hotpoint for Hotpoint at this time which were very reliable and highly rated by users and engineers.
In the late 1970s and into the early 1980s the company had a range of washing machines which used an induction motor with a clutch pulley system. Again this range proved extremely popular and very reliable.
During this period Zanussi Professional, the catering range of appliances for commercial use, became a separate division in its own right.
In the early 1980s Zanussi launched the Jetsystem washing machine range to great acclaim whilst at the same time running the “Appliance Of Science” advertising campaign which is acknowledged as one of the most successful marketing campaigns of all time, in fact still remembered by many today. This gave the brand the impression of being forward thinking and innovative.
Zanussi has recently been rebranded as Zanussi-Electrolux in line with many other Electrolux brand names. Since that time many Zanussi appliances share common components and parts with the rest of the Electrolux range, primarily Electrolux, Tricity Bendix and AEG although it is worth noting that the “John Lewis” branded machines sold by the John Lewis Partnership in the UK are effectively rebranded Zanussi appliances.
In the late 1980s Zanussi launched the split tank design known as the “Nexus Tub” design which endures to this day with little change. The tub, base and certain other parts are made from a plastic material known as “Carboran” which can be re-used several times if recycled. To this day neither Zanussi or Electrolux has provided any way to return this material for recycling purposes.

Up until the end of the 1980s Zanussi service was run from Slough and was a network of independent repairers who gave an unparalleled service level. It is generally acknowledged within the industry that this service network was the best that there has ever been in the UK.
In the early 1990s Electrolux instigated amalgamating all its UK brands under one service entity. This entity was split, dependent on region, between the Zanussi service agents and the local Electrolux Service Centre. In general those in a high population density area where given to the Electrolux employed centres. Tricity Bendix, Electrolux and AEG as well as Zanussi were all to be serviced by the one network.
This was changed in the late 1990s and early 2000s as Electrolux sold or gave away the regional service centres, generally to the existing management or to area managers to run as independent businesses.
This service network was rebranded and became Service Force which still exists today but is, once again, all operated by independent service companies who repair and supply spare parts for all of the brands.................

 ..........................when the president Lino Zanussi died in a plane crash in June 1968 - Zanussi
Industries was the first Italian manufacturer of white goods and employs approximately 13000 employees.

When the Zanussi group of Pordenone lives a first phase of  financial stress then Lamberto Mazza, who succeeded Lino Zanussi, decides to liquidate some social funds with share capital held by Guido Zanussi  causing an outlay of 16 billion lire of that era.

Despite the Huge outlay to cope with such a withdrawal, the group aquired, in the course of 1970, competitor like Zoppas the other big Italian manufacturer of household appliances, which was,
significantly in debt due of an acquisition of Triplex in Solarolo and a construction of the new plant in Susegana.

The Zoppas, whose factories were located in Conegliano Veneto (TV), has a history quite similar to Zanussi: it is in fact founded by Ferdinand Zoppas in 1926 as an artisan company repair of wood-burning stoves and then spread widely and rapidly under the leadership of his sons Augusto and Gino.

Zanussi president, Lamberto Mazza, alleged a plan to achieve an optimal size to compete at the European level if not the world, strengthening the shares held by Zanussi on the Italian market to avoid  the entry of foreign competitors (in particular the U.S. Westinghouse).

The Financial stress imposed on Zanussi by acquisition of Zoppas and, simultaneously, the increase in the incidence both of labor costs and reasons of rise up of activity intensity (In the space of a short pass from 13,000 employees to 24,000 units?)  is faced with:

a. the sale to the German AEG-Telefunken
an amount equal to 25.01% of the Zanussi S.p.A.
(The operational holding company of the group)

(The share of ownership AEG-Telefunken is subsequently recognized in 1978 by Voet-Alpine.)


b. to loans from Italian Istituto Mobiliare
(IMI);

c.
about a loan of about two hundred million marks
disbursed in 1974 from Dresden Bank.

The union conflicts, the impact of labor costs (in 1974 Zanussi occupies nearly 31,000 employees), the Debt contract with institutions credit and the first oil shock induce Lamberto Mazza to start a rapid process of diversification The core of this strategy is, however, the belief that the market of appliance White has come to its stage of maturity, with a saturation level  and the consequent reduction of typical viability.

Therefore, in this back of years Zanussi invests substantial financial resources to acquiring control of businesses;

(The process of growth of Zanussi,  nevertheless sees the creation of new realities companys as a result of corporate spin-offs.

Considering, for example,

Zanussi Grandi Cucine SpA, Zanussi Grandi Impianti
SpA, Air Zanussi SpA, Zanussi Components for Construction SpA, the Industrialised Building ZanussiFarsura SpA to subsidiaries Iberian Zinsa-Zanussi Industrial SA Compania SA and Industrias Electrodomesticas,
and Lastly Anglo-Saxon Iaz International Ltd., was established in 1979
well as the company insurance and financial intermediation
group, called Infinas S.p.A.) with few exceptions   activities not related with the core business.

In particular, remembering the concentrations of corporate sectors relating to paper (Paper Mill Galvani SpA, Cartopiave SpA and subsidiaries Cartosud and Silica), electronic (Ducati Electrical, Electronics-Inelco), construction (Seicom-Building for Integrated Components SpA), metallurgical (Smalteria and Metallurgical Veneta SpA), hotel (Borsa SpA) of furniture (Galvani Porcelain SpA, Sambuceto SA, Meson's Spring SpA SpA and its subsidiaries and Pagnucco SpA), components (Ilpea Gomma SpA), photographic equipment ( Fotomec San Marco SpA) of entertainment
(Udinese Calcio SpA) and solar photovoltaics.

(The investments of Zanussi happenned sometimes even in the indirect form
 which is made through the CISVE (Industrial Consortium
Economic Development), founded by Lamberto Mazza in quality of
President of the association of Industrialists of Pordenone, as well, since 1978, through the Industrial Finance SpA, a company financial system constituted specifically for that.)

the Organization Company is  formed in a matrix in which the divisional activities and  are then grouped into the following sections:

1.apparatus for heating;
2.components for Building;
3.solar panels;
4.apparatus Idronet (for potability of the water);
5.components;
6.apparatus different from electronic television sets.

But when the financial situation Worsened in 1983,
Zanussi family the shareholder majority, distrusted Lamberto Mazza replacing him
initially with Umberto Cuttica, former manager of FIAT,
then later with Gianfranco Zoppas, husband of Antonia Zanussi and son Lino.

The corporate reorganization plan was then prepared by the new management and was designed to focus the now scarce financial resources in the core business of group, to continue or to divest a number of activities not closely related ( Air Zanussi, Zanussi Construction Industrialized, Zanussi Electronics, Paper Mill Galvani,Pagnucco, Fotomec, New Cartopiave) , thus preparing the field for the sale of the Entire group to Electrolux, the Swedish multinational leader in field of white goods.



Stern / REX / Zanussi / Seleco (WAS) is an electronics company based in Pordenone, Friuli Venezia Giulia, Italy. It is part of Super//Fluo, who bought the rights in August, 2006, along with Brionvega and Imperial.


Sèleco was born as in 1965 as a spin-off from the home appliances maker Zanussi. In the first years of his life, Seleco produced almost black and white televisions with the Zanussi or Rex brand. The company was being sold in 1984, and was first acquired by Gian Mario Rossignolo. He first became president and then main stockholder.
During the 1980s, the company launched worldwide marketing campaigns and began sponsoring some of the most famous Italian soccer team, such as Lazio A.S..
During the '90s, the company was mainly concentrated on the production of pay-tv decoders for TelePiu' , but in 1993 suffered from a loss of competitivity. With the intent to reshape its position and to get gave new life to the company, Gian Mario Rossignolo bought Brionvega from the Brion family, the founder. This attempt get to nowhere, so the company was forced to declare failure in 1997. During the years, Sèleco has passed through ups and downs, at the end being overcome by the continuous changes in the electronics world.
After the crack-down, the company and all its interests were bought by the Formenti family. That gave life to the Seleco-Formenti Group, owner of the rights for the brands Sèleco, Rex, Phonola, Imperial, Stern, Phoenix, Televideon, Kerion and Webrik.

The Formenti family re-launched the company with the production of CRT-TVs. In 2000, the company suffered of a strong crisis, following the price dumping made by Turkish manufacturers. That seems to led to end of the Sèleco and Brionvega story, as the Sèleco-Formenti Group was forced to liquidation.
In 2004, the rights for the radio branch were bought by Sim2 Multimedia, and all the television interests (for the brands Sèleco, Brionvega and Imperial) were acquired by Super//Fluo in August 2006.

THIS INDUSTRY IS TODAY DEAD !!!!
