Remove the 7Y4 rectifier tube and power up the set again. Doing this will remove the high voltage load from the power transformer. See if the transformer still sizzles and gets hot. If it does without the rectifier tube installed then the transformer is fried.
You may have a shorted 41 output tube which could be loading the power supply, but try removing the rectifier first. If all is well with the rectifier removed then reinstall the 7Y4 and try removing the 41 tubes next.

Yep the dim bulb test is OK but I'd definitely replace all those electrolytics before I did it. Since those #47 conden...klondike98 — 09:18 PM |

The resistor is a 2.2 Meg, it was the last one I hadn't replaced. The broadcast is coming in after replacing it.osanders0311 — 09:09 PM |

What does the resistor measure? I think it should be 3.3 Meg.
