Was working, now trying to burn up!
#2

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.
