I just got done with the recap of this radio and when I powered it up on a Variac I only get a faith buzz out of the speaker if the volume control is up most of the way. I touched the grid caps on top of the tubes that have grid caps on top and only two make noise. The 6Q7G makes a buzz thru the speaker and the 6K7G (if amp) makes a click thru the speaker. The 6A8G (detector) and the 6K7G (rf) make no buzz at all.
I re-tested the tubes on my tester and they're good. Th rectifier and output tube do get warm and the transformer stays cool.
I'm new to troubleshooting a Radio this old - only worked on AA5's before this. Would the next step be checking the voltages ? Or am I overlooking something simple?
