Restoring a Predicta Tandem
#12

AWESOME NEWS!!!!! I was starting to doubt being able to do this. But I kind of gave my self some hope last night.  Ive been pretty discouraged since the tubes stopped lighting. Well I replaced C1 because it was visibly leaking and I finally got a capacitor meter which showed it as shorted. Then I jumped out the Fusistor and I got A screen!!! Granted it was just white and had no sound just a slight hum. But it actually did something. Oddly enough after running it for a couple minutes the thermistor now reads correctly. I didnt get to check the filament dropping resistor yet. But the point is theres hope now. Im guessing since there's no real image and no sound I probably have no tuner? I slid back the rubber boot on the connector and back probed the wires while the set was running. I got 56V Ac on the White, 13v Ac on the Green, 22 V AC on the Red, 18V Ac on the Brown, and 375V on the Orange. Do those seem to be in spec? Also the tube in the tuner farthest from the knob is kind of Dim compared to the rest. The photo fact doesnt tell you what tube to replace it with though, and the GE tube in there has most of the writing worn off...

Radioroslyn  where did you get those fusistors they look just like the originals?
