Admiral Combo Chassis - Dead LV Rectifier?

[Nuke]

You got it - just figured that out myself in the garage. The 6x5 lights in TV mode. OK - so I know I have to figure out why no audio or hum. Guess I will start with the audio transformer. Also crossed speaker wires etc. BTW - I am doing this with a 300 watt dim bulb and variac. That will restrict alot of voltage.

I can see why people avoid combo models - many points of failure and huge schematics. But what a challenge. This is no AA5! But my approach will be to work on things obviously not functioning to see how much life is actually left in this set. So far it looks like the transformer is good and the CRT lights. If either or both were bad - the set would be trash.
