Perhaps the most interesting piece of my collection, a color TV, year 1974 hybrid that is valves and transistors. 20 ", 7 diode varicap channels without remote control, average power compsuntion 300W. I found him to steet next to a garbage collection point. at first it Did not work. The failure was the valve py 500 KO. The cause was given by a previous bad repair, in practice had spent two by resistance from 1.5 Mohm in section HV. reinstated the cause and the replace pl 500 he resorted and the color TV to work wonderfully, only that after about one year occurred another defect. ignites with filament ok and HV present and with audio ok, but we see nothing Nos on the screen, as if lacking the signal luminance. chrominance believe that there is now if I have a little time to devote to try to eliminate this failure,
I must say that among all the color TV I've seen, this has an image and color superb
