Got it! I had a sneaking suspicion all along that the OSC coil wasn't working, as I ohmed out both the IF cans and they had solid and even values so I knew they were good. So, seeing there was only a mica cap and two wires connected to the OSC, I disconnected it and installed one of the universal AES OSC coils. It started receiving stations all across the dial right away. Tomorrow night (while you're luxuriating in Kutztown) I will be figuring out how to mount the new coil under the chassis.

And yes, you have become my Professor LeBlanc! No, no, no Missure Benny!!

Thanks again for the nudge in the right direction, my friend.
