Help with NC-183 D
 

I have a NC 183D that has a couple of disconnected components also seems to
have a mod where the 6J5 used to be was modded to take a 8SN7 ???
Has anyone heard about this mod?
Will appreciate any help or input, I can even email digital pictures of the
underside if that would help.

Thanks in advance....Gil

Just a guess, but might it be a product detector?

6SN7? Could be wired ot work as a product detector with BFO injection,
or AM detector without. Ed Engelken did a similar mod to an S40.

6SN7. Which is actually two 6J5s in one glass octal envelope.

Never heard of any mods like that but it could be a product detector. Another
possibility is that a former owner had a 6SN7 but no 6J5s and rewired the tube
socket to use one side of the 6SN7
