National RK 11

The National RK 11 was the first television set to go through Electronica in Bucharest: the version for the East European OIRT standard of the Japanese RK3 model (made in Japan for the American FCC standard), prepared by the Japanese for Romania [1]. It has a 59 cm, 110° picture tube [1]. It was followed by the Național VS 43-614, made from complete National kits [1].

Electronica also turned to Matsushita, the best Japanese maker of television sets (brand National in Asia, Panasonic in the USA and Western Europe) [1]. The first set to go through the works was the National RK 11, the version for the East European OIRT standard of the RK3 model, prepared by the Japanese for Romania [1]. Complete Japanese kits for about 50,000 sets a year were then contracted [1]. In all, about 240,000 TV sets were made with Japanese kits, with 15–16 tubes, 6–10 germanium diodes, a 12-channel turret tuner, a common video-sound path, 1.8–2 W audio output, picture tubes with 90° and later 110° deflection and electrostatic focusing, 16–18 kV accelerating voltage, and 43, 47 or 59 cm screens; they drew 160–180 W from the mains and were reliable [1].

In the source table, video sensitivity is given for 6 V rms on the picture-tube cathode, sound sensitivity for 50 mW output, the selectivity values are, in order, the rejection of the own sound carrier, of the lower adjacent sound carrier, of the upper adjacent picture carrier, of the IF and of the image frequency, and the audio response at −3 dB [1].
