I performed the tap test again, with inconclusive results. I went ahead and connected my signal generator and was able to easily peak all 4 IF trimmers using the AVC voltage. At first screws were stuck and there was some crackling as they were turned but that went away as they were exercised. So far, no volume drop and selectivity has improved. I am thinking that there may have been a little oxidation on the trimmers.
I will start a new thread for antenna ideas….
