37-630 Possible Silver Migration Problem
#1

I just completed the rebuild of a 37-630 console and it works great with one exception. I am getting the typical silver migration noise intermittently. I have been dealing with differences from the Run 2 diagrams from the docs on Nostalgia Air's site and the version I have. I worked thru it even though the alignment of the compensators are laid out differently (less of them). Still figuring out which is which in the RF and Ant sections.

The version I have does not have caps 38 and 42 visible (110pf) as an example.

My question is are there caps inside the IF cans that I am somehow missing from the schematic I have? If so, what are those values that probably need replacing? If not, any thoughts on another direction?

Thanks for everyone's help.
