Sizzlin' Zenith SC 400

[leadlike]

Just started to put this Space Command 400 back in working order last week. I have replaced any worn or outright bad tubes and did some resistance checks and found nothing out of the ordinary. Most of the lytics have been replaced with new units under the chassis. Those caps, while newer, were probably put in about thirty years ago.

I did a variac slow start and after about fifteen minutes on twenty volts ac, I detected a 'warm' odor, about how the set should smell when it is running full blast. I powered down, felt around and found that the choke was pretty hot, about 110 degrees F. Closer inspection reveals the breaker was jumpered across. Clipping that out, it now goes into protection as it should. I have a full set of new electrolytic caps on their way now, the power diodes don't appear to be shorted. Is there anything else I can check on while I wait for my caps?

These color tvs are really different to me, as someone who has only worked on radios and B&W sets! I really hope to get this one going as local roundies seem to be scarce.
