Today, I replace resistor #28. Hmm, this chassis to ground resistor has all the cathodes on one side of the resistor and everything else on the other side.
I put a smaller antenna on the set and used the newly discovered antenna connection and it now plays non-distorted but local 50,000 Watt AM station that is 3.5 miles away is basically flooding the radio. I'm going to need to more finely tune the IF and local osc. instead of by ear and hopefully get more stations.
Is it possible that the local osc might be off 455 and on a frequency that is harmonically related to the local station?
