[ARC5] Audio transformers.

OK. I am confused. I am trying to replace the audio transformers in a couple of the receivers 
I am working to resurrect here, and am not sure which audio transformer goes where.

I have a transformer numbered 5631, which is in what I ***think*** is (or was) an R-23/ARC-5 
which is so badly hacked that it will take an unusual amount of work to resurrect it. (It was 
modified to tune ONLY to a VLF station on 22.3 KHz)

Would that be the appropriate/correct transformer to replace one missing from a CBY-46104 
receiver?

What about an R-25/ARC-5? Which is the correct transformer for that one?

Does anyone have any audio transformers they would part with for a reasonable sum?

I absolutely cannot figure out why anyone would rip the original audio transformer out of 
these things!

It looks like the SCR-274N receivers all used one of only 2 different transformers lettered ES-
******

I cannot find the necessary info in the only copies I have of the SCR-274N units and the 
AN/ARC-5 units.
