It's easy enough to describe with words: 2 microwave oven transformers;
their primaries in series, connected to 240v. The secondaries replaced
with 2 turns of the heaviest wire that will fit & connected in parallel.
That's it.
Interesting; thanks, Bob. Any of the MOTs I have "played" with saturate
above 90VAC with the secondaries shorted; how much input current are you
seeing on this thing?
