Thanks, don't relish more re-winding, but the one I did was pretty rotten to the touch. I have good plate voltages through all stages, does that say anything about the coils? I can send an RF in the early stages and AF in the later ones and get at least a low volume signal through the set. An odd thing to me, I have no cathode voltage. Should be around 20 volts. Is this telling me something? or am I measuring it wrong. Tubes should be good. They're tested on my Hikok and swapped in and out to be sure.
Thanks Phorum.
Alan
