Hello Lawrence,
I look a quick look at the schematic for your radio and the first thing that popped into my mind is the AM/FM switch. Section 4, contacts 7, 8 and 9, of the wafer switch selects either AM or FM by shorting out the unused secondary. You're going to tell me that you have cleaned that wafer switch, but give it another go with the cleaner, preferably Deoxit D5, and a brush. We've had people do the cleaning 4 or 5 times before getting results.
