I have an AC-3 power supply for sale that was used on a TR4 I recently sold. The buyer didn't need the power supply. It is untested and hasn't been powered up in a number of years so I can't vouch for it's working condition as I don't have a variac yet. FWIW, it was working before it went into storage, it belonged to my late father. Feel free to email with questions, requests for pics, or offers. Cosmetically, I would rate it's condition as average.
