The central problem is the high cost of cores, usually around $550 for a 10 kVA xmfr. Next, add the cost of the copper wire and expensive aluminum, and you are quickly up to $700 just for the material. That's why most experimenters just purchase a used pole xmfr for $200 or less. More economical and you don't have to re-invent the wheel. Dr. Resonance
Yes, DC.This is one thing I have to commend you for. Supplying pole pigs to the coiling community. It`s a giveaway, and I have sorely wished it would be possible here in Europe, but It`s all 3phase here.
