I have since learned that the speaker that was in this set is not the correct speaker.
It is part no. 49-152AB. A good friend of mine tells me that speaker is actually used in a 5-R-135. Its field is rated at 2125 ohms, more than double the specified 1000 ohm field of the proper 49-117 speaker.
So, after replacing one tube, some capacitors, all resistors including the Candohm, attempted repair of the 1st IF...it still needs an antenna choke, 2nd (and possibly 1st) IF transformers, an audio output transformer...and possibly a speaker.
Hoo boy.
But I'm committed this far now, so I am going to see this project through to completion.
