38-2 Audio Yes Signal No
#9

So here's the result. Craziness! LOL. we used a signal tracer and found that the radio was not getting signal to the IF section. All coils were good. We found tons of loose tube socket pin sockets and as were the case with these quite a few were brittle and cracked off partially. We were able to fashion good connections with the remaining material. Right now, my friend has it. He got the IF to work but says it is still not producing signal (no stations through the speaker)? He's going to work on it again tomorrow. The center tap of the volume control now provides feedback when touched. Any ideas? We checked resistors, caps, coils, tubes (checked to make sure the 6J5 G's were not microphonic) found two block caps I accidentally shorted by leaning cap wires together and did not notice. The set is a run no. 3 and has the tuned permeability IF's?  I am, as well, looking for a dial surround for it that has the original paint on it. Someone stripped it down to the brass back in the 70's or earlier due to some Bicentennial color scheme tabs inserted in the pre-set ring. Any ideas what might be killing the signal?
