Ok, I just moved my signal tracer tracer to the plate of the IF tube and connected through a small cap - now it tracks the radio! I can also hear the static through the signal tracer (it is more sensitive than the radio), so I'd say I have it narrowed to the IF stage, maybe more specifically, the IF transformer. I will do some careful checks in this area, but the only thing I see on the plate circuit is the primary of the transformer (#20). Sounds like it's time to pull the IF transformer. To double ck, I went back to the IF grid with the tracer - same, does NOT track the radio and I dont hear the static. I double checked the plate and cathode voltage (no changes), but this may be such a small change that it affects the signal, without affecting a measurable voltage. Just to post, plate sits at 305v, cathode is at 10.6v, G2 is 119. I still have the volume control bypassed with a series of fixed resistors. Thoughts?
