I have a 39-17 that needs a output transformer, the original part number is 32-7980. I bought it off of ebay and it came with most of the wiring dried and flaked off. The wiring on the transformer can not be sleeved. Anyone know of a replacement output transformer. According to the radio specs the input impedance is 8K and the output Z is 3.5 and the output is 2 Watts. I read some where that a Hammond 125 CT would work. Any suggestions?
Thanks,
Tom

I don't have the sch; and it is not on Nostalgia, so if you have the link please post it.
As for the xfmr, if it is pushpull the CT version of 125 will do, if SE then the SE is needed.

This one is about 1/3 of the price of the Hammond one.

So your output is SE?
