MrFixr55 I am using the second schematic, the one with the X parts as that is my radio. The 39A and B are 16X, containing 110pf caps that are in a bakelite block. I had already changed them with silver micas. Having to use two different schematics sure makes this harder. Some sections are on one and some the other.
The coils in both IFs are all good. I had checked them a while ago.
No caps in series with probes. I will try again with caps. I was told a while ago there were blocking caps in the tracer. Not sure about the ground though.
I don't know how to measure the difference frequency. I don't have a scope so the best I might do is a frequency counter but I would not know how to do that either.
As for the non peaking compensator I'm wondering if the internal cap might be bad. The schematic does not list the value for them except for 2XD (110pf) which I changed.
If RF alignment is off could that render the AVC inactive? I'm wondering if I should put the radio aside until I get my dial and then I can do the RF alignment.
