Ron:
Wow! This is going to be very strange.
The schematic shows 8 tubes, but notes that the 40-180 does not use the 7A6 tube.
They even show dotted lines for the tube and it's connections.
I assume that since the 7J7 and the 6J8G are mirror images of one another, that the factory wired the set
for that tube to be used as the Det.-Osc. rather than a 7J7. Is that correct?
Is this common in older sets, or is this an aberration?
BTW I made the contact you suggested about the Shield, and he has given me a price and is looking to see if
he can locate the specs for it. I'll probably have him create a new one for me, and will work on AA5 radios in
the mean time as I think this one will be quite a challenge.
Thanks for your help.
