I did some surgery on the 2nd IF transformer. Took out the two caps across the transformer coils and replaced them with two 82 pF caps. Pic shows the first new cap in place and the one remaining old cap at the bottom. Buttoned it up again and ….. nada …. No signal at all coming through the 2nd IF transformer now. I was about to take it out and try some 100 pf caps when I thought about an observation I had made while signal tracing. I recalled getting signal at the output of the filter circuit in the 2nd IF can… probably shouldn’t be seeing that and decided to try disconnecting that at the point where the slate colored wire (SL) connects to the 1LD5 filament line. Heard signal now at the speaker!! So that filter circuit must have failed. I was able to align the 1st and 2nd IF transformers now although the only AM channels I can get are the local ones. I think this still needs more work but it will be the next guy will have to do it.

IF can wire size and Rubber mounts?

Renovated Radios do carry what you need.
As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM |
