Yeah, the unit otherwise works, and there's no 120/240 switch on this unit. I've checked the transformer winding outputs and they're the correct voltage. I'll try disconnecting the wires from the VFD and see if they read the proper voltage then. Maybe the 1.3v is because of the load of the VFD. If the VFD cracked or leaked somehow would it still draw current even though nothing is displayed?

I'm assuming supplying 5v DC to the filaments for a second or so wouldn't be a good idea. I don't really have an AC power source that I can generate to test otherwise.

Hmm, I do have another cassette deck that I can temporarily swap the VFD out of. I can try that too.

Charles.
