It’s been a while since you posted, so not sure if you still need info. But, yes, I just recently completed a full disassembly and currently working on restoration. Filament voltage tested at just under 1 volt after bypassing two on the 54 thermocouples. This was with a temporary wick so not full flame. Uses zinc antimony/constantan for the thermopiles. Look lo Voltages are 1.2, 9v, and 90v. Tge 90v is going to be a challenge. Lots of opens on the thermopile. Let me know how you made out on yours.
