Well miracles happen. I checked the plate, screen and grid voltages at the 41 tubes and all seemed good and I had a very loud hum when touching the center tap of the volume pot. I haven't rebuilt the top of the chassis yet except to mount the tuning cap so I turned the chassis right side up and tried tuning by hand with the wheel. I wish I had a picture of the look on my face when a local AM station came in blasting loud and clear! The 7G7 RF amp tube that came with the radio tested very weak so I didn't have it installed. Ironically, reception deteriorated badly when I installed it.
The chassis was in rough shape when I got the radio and the previous owner(s) made several incorrect wiring/component changes. I can't believe it's actually working. I still have the rest of the chassis reassembly to go and I have a stripped cabinet awaiting but I think the hard part is done. I've been taking pictures along the way and I'll post some when I finish.
