I'm slowly making progress on the chassis. I discovered that the audio coupling transformer is also a replacement but tests OK. The same cannot be said of the antenna coil though Icon_sad

What I find really strange is that every tap of this coil is open. Someone had connected a low ohm flexible resistor from one tap to ground. I assume that was an attempt to restore reception.

Surprisingly, the antenna coil in the modified chassis is good. So I have the option of repairing this one or swapping it out. Either way, it's not going to be fun. So many connections to deal with ...
