Greetings from Minnetonka, Minnesota USA.  I would appreciate a tube layout for this model.  My radio found me with no back panel and I would like to confirm that I have the tubes properly placed.

 

Thank you!

I don't have a tube layout. But I was working on a set where I didn't even know what tubes there should be!

Consult the schematic. I haven't so I may make a mistake:

EF80 EC92 ECH81  These 3 are  for VHF and AM Mixer/Osc. The EC92 is the only 7 pin. The ECH81 will be beside the AM tuning vanes.

EF41 This is likely IF amp so between the pair of IFT cans.

EM71 Magic eye on panel

EAF42 EABC80 Detectors for AM & FM. Just after last IFT can. Different bases so can't mix up

EF40 phase splitter to drive one or both  EL41 EL41

EL41 EL41 Presumably push pull Audio Out. Anodes connect direct to the Audio O/P transformer.
