I recently cleaned out my warehouse to eliminate the rent payment. I had about 10 MOT's that I had collected over the years. There were two pairs so I decided to test them. The ratio from primary to secondary (not using the heater winding) is about 20 which works out to a 3200 ohm primary for an 8 ohm load. I wired each pair into a SSE amp and tried EL34 and KT88 tubes. They were virtually useless until I hammered the shunts out, then they were just lousy. Both kinds had poor frequency response, the larger pair didn't even make it to 1KHz. I decided to punt. and all went to the metal scrapper.
Too many transformers, not enough space.
Thanks, that means one less experiment none of have to do. Seems the iron might be salvageable for a power transformer but that is it.
This is an OT (Off Topic) not an OT (Output Transformer)
but is a feasible alternative use of a MW Transformer
I think that it gives good results because if you Google about it you can find more than a guy has do this

Not a direct use on an amp, but may be a related use on building it

what i had in mind is just to use the iron, the copper wires had to go....obviously, we can not use those traffos as they are....
unless you can get several vertical sections, the MOT's are useless for audio as is....
