Tubegroover and Detredwings, thanks for the invaluable advice; I would replace the transformer my self if I could find one. CJ won't sell one, and I don't know where else to go.
Since the mod people can probably get a transformer, that could be included with the mod. CJ was not specific enough for me; while their minimum for inspecting the unit wasn't bad, there was no guarantee in regard to repair. There have been complaints (not against CJ) about no follow through after submitting up front money. New scams seem to be contagious and they come in waves.
I'll contact Bill Thalman in Virginia, and we'll keep each other posted on progress; thanks a lot.
