 What is the value of the rheostat..I may have it in my junk box.
I'm guessing the rheostat is from the HF TBW...I have a parts radio but it is buried deep in the glacier of stuff in the stufftorium. If I can get to it it I'll let you know.

Hi All

One of the wire wound pots for filament control on my TBW-4 has a break in the wire.

I cleaned the break and added a parallel wire and attempted to solder the two.

The solder will not stick to the wire on the pot.   I tried different iron temperatures etc but to no avail.

Any ideas as  to alternate ways to fix this?   Photos attached.
