My "new" Zenith Porthole set 28T961E

I attempted to bring this set up on the Variac, it has a shorted cap, it's drawing about 1 amp at 70 volts and the main filter on the power supply chassis gets really warm.

The recapped chassis from my 16" draws a little less than 1 amp when it's working at 115v.

Nice find. I believe that's from Zenith first line of production TV's in '48. A classic set. Good luck with it!
