Thanks, I was hoping that, if nothing else, there'd be an option like that.

Both of the power transformers in this set have an octal jumper plug that can but rotated to use either 115 or 230. The two transformer options are listed on the parts list, but the schematic doesn't show the jumper, just a single primary. The other thing I found, just on this transformer, is that someone had replaced the recifier socket and it's not wired correctly for a 5X4. Maybe they wanted to use a 5U4? Don't know.

You're right, this set is in great physical condition otherwise and well worth some expense. Have you got even a ballpark guess as to what they'd charge if I sent them the original & a schematic with the specs?
