UPDATE: I figured out what my problem is, its the IF Cans, apparently at some point in time in this radio's history both IF Cans were replaced, and whomever did the replacement installed two IF Cans of with two Different IF Frequencies that were completely different from the original IF Frequency of the radio!
The 1st IF Can was replaced with an IF Can with an IF Frequency of 455 kHz and the 2nd IF Can was replaced with an IF Can with an IF Frequency of 475 kHz, and the radio's original IF Frequency according to the Riders was 465 kHz which might explain why this radio isn't working right.
When I feed a signal through my antenna hookup on the radio using my signal generator I can hear the signal coming through albeit very faintly (I have to have the volume turned clear up to hear it) and with the signal Generator's High Output signal being used the signal comes through at a somewhat normal volume level, which means that what my radio's problem is isn't the tubes or a dead oscillator coil or too weak of batteries, what the problem is, is the radio is trying to operate with two IF Cans of different frequencies.
So I'm not quite sure how I would fix this issue...
