two 1950s GE sets in metal cabinets

[Adam]

I switched to working on the '56 GE from my RCA KCS47, being fed up with problems with the RCA I couldn't figure out.

I completely recapped the GE. At first the GE had no vert deflection, and only very little horiz. Vertical output transformer looked bad. I replaced the vert output trans, which got me back my vertical.

But the horiz is only about 2" wide, also way, way off frequency. The voltages at the horiz osc and output tube check out. But the boost voltage is about 100v low, and the HV is only about 1.5-2kv. HV rectifier tube was very weak and damper tube slightly weak, but swapping those made no difference. I checked across the flyback and also the yoke with an ohm meter, and it read what it should. Then, I went to adjust the horiz osc coil and the slug was stuck, I look at it, it's broken, but I try to turn it anyway, it broke worse, shorted something, sparks flew out of it, and it made such a loud noise my ears rang for nearly 30min afterwards. It also took out the horiz osc tube, but no other components seem to be damaged.

I thought this set would be an easy one to fix, a nice break from that RCA KCS47, but it's proving to be much the opposite.
