Motorola ts907 low hv

[timmy]

Changed all power supply caps now all nichicon caps big increase in the b+ but it’s still being pulled down to the point where the horizontal oscillator won’t run then it draws even more and the hot tube again red plates so on the bench this don’t happen but after I put it back in the cabinet and plug everything in this is when it happens so at this point I’ll have to sit on it for now. Baffling to say the least when the oscillator runs I have excellent hv but that’s only when I first plug it in once warm up pull plug put back in no oscillator and big draw. Oh well. The veritcle centering pot after turning more then half then it varies very little I have to think maybe it’s shorted it’s wire wound and has a 385v feed to it or possibly a shorted turn on one of the sections of the verticle output transformer got to think of everything at this point.I guess now I’m going to check voltages on the tubes.
