Don't know, maybe smarter people can tell me how but think the wire that's
used is something like the stuff they use on heater elements so it can not
be soldered, if somehow you were able to get a couple turns un-wound maybe
you can just tie them together but looks to me as far as the power pot is
concerned, its game over!

How are you doing the entire T-202 mess? The original circuit for 800 cycles
had that pot (R-201) and all those weird power compensation capacitors
switches and all that stuff. I did separate filament transformers for all
the tubes except for the weird 2.5 volts for the 843 and a separate huge 10
amp transformer for the ten volts for the 803, used the power stat or
whatever you call those huge wire wound pots just on the AC primary of the
ten volt 803 supply, the good thing if you got to replace it you don't have
to get an exact match, just something that fits in the same hole.
