Did get the high voltage reading off the speaker plug on the input side. Coming off the E cap, because your right, there is nothing on the output side with plug disconnected.
On checking the caps as you say, one side to the other, are you testing for a shorted cap?
I do have a cheap little cap tester that will test the value of the cap too.
When the speaker is plugged in the voltage checked on the input side of the voice coil from that first e cap is 250 approx.
SO it's ok from the power transformer,to the voice coil, but then gets lost somewhere between the voice coil and the output transformer.
Puzzling thing to me is not only the low voltage on both 42 tubes, but the fact that the voltage is so much different between the 2 tubes.
Oh well, I only paid $30 for the radio, but have logged lot's of hours on it which has only made it worth $30.
It is a good way to learn a little about trouble shooting though.
I need the experience.
