[pepper]

Hello all need help identifying this power transformer it came with two heathkit 51-58 outputs but I do not know if this is a heath kit power transformer any help would be greatly appreciated

The Heathkit 51-58 transformer was used in the AA-100 integrated amplifier. According to the manual, the power transformer used in the AA-100 bore the part number 54-89. Don't see that number on the end-bell of that transformer, so it might not have been meant for that amp.

That's a Freed-built power transformer- and it looks similar to what was used in many of the Harman-Kardon integrated and power amps.

However, I can't quite match that part number. It doesn't match any of the HK PT part numbers I can find on a quick search. Not to say it isn't HK, but I can't make it match anything I find, so far...

Regards,
Gordon.
