The ELECTA (ZANUSSI) EX24 is A 24 inches B/W screen with plastic front and 4 programs preselection with potentiometric tuning search.
Quite uncommon the "design " of the knobs used for settings like bright contrast volume and on off knob.
In the on off knob there is integrated another switch used for activating a color killer filter to avoid some noises on picture during color transmissions (Burst Key Pulse).(Colour subcarrier suppression key, to remove colour subcarrier fully.) The composite color signal includes a chrominance component and a luminance component, the latter being comparable to a monochrome signal representing the brightness variations of the image. The chrominance component consists of a subcarrier wave and its modulation sidebands modulated in phase to represent hue and in amplitude to represent color intensity. In addition, the composite color signal contains horizontal and vertical synchronizing pulses, and synchronizing bursts of the color subcarrier. In transmission the color subcarrier is suppressed, making it necessary to reproduce the subcarrier at the receiver to permit demodulation of the chrominance components. Therefore, the synchronizing bursts of the color subcarrier are utilized to control a subcarrier oscillator in the receiver operative to provide the desired continuous wave signal for subcarrier reinsertion. In a color television receiver, after amplification and detection of the composite color signal, the luminance and chrominance components are separated and applied to luminance and chrominance channels, respectively, of the receiver for further signal processing. The synchronizing bursts of the color subcarrier are also applied to the chrominance section of the receiver. For a monochrome broadcast, the monochrome signal is processed in normal fashion through the luminance channel of the receiver and is applied to the picture tube to recreate the black and white image. However, for b/w tv sets it is necessary to disable the chrominance channel to avoid spuriousdistrubances in the b/w picture. Under optimum operating conditions, the color killer functions as an on/off switch; that is, the chrominance channel is completely disabled. To accomplish this function properly, the circuit should have relatively sharp switching characteristics. When a black-and-white signal or a color television signal of insufficient amplitude is received, color reproduction should be impossible. In the known receiver employing a color killer mentioned in the preamble the drawback occurs that the color killer does not always switch off at the same intensity of a received weak color television signal. It is the object of the invention to remove this drawback.
ELECTA is (was) a brand name property of ZANUSSI.
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.
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, 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 !!!!
