The chopper is 240, single phase. the rotator motor I believe could be single phase 240 or 3 phase 240. hopefully you get single!.
the chopper can be run off of 120, just will sound lower and may draw more amperage.

So I did look at my series C Thunderbolt manual. There is an autotransformer used to set the tone frequency. Basically a multi-tapped transformer that would output different voltages on different taps. So I would use extreme caution just hooking it up to the wall and trying to run it.

All it is is two wires...cut the end off an extension cord, wire nut white to white and black to black and you're good. It's not rocket surgery.

BTW, chopper level 1 is 120V so a standard wall outlet will be fine. As long as you have everything hooked up right you really have to try to blow something up...

Most Thunderbolt chopper motors are ran on 120~240v, with chopper level 1 to 7 the voltages in between those voltages. Running it on 120v should be no issue.

That’s run off a wall plug. The first blast didn’t have the wire connected right. The second blast (2:30) was hooked up all good and went off no problem.

EDIT: we did use a surge protector for the switch too.
