Electrical Gurus - Help me fix this Puch electrical tester

Recently scored the OG Puch electrical test tool (thanks @jackerz!) but the potentiometer knob is frozen and place and unable to turn. Could any electrical gurus point me to where I could source a new one?

Pics below. Three wires going in, has CTS. 7832 and 2P1556 stamped on the bottom.

Why not pull that one apart and see if you can't refurbish it ?

Might just be a bit of corrosion inside .

Ebay has a couple that look like they might work , but ???

My buddy is gonna loan me some Deoxit to try and refurbish this one but I'm trying to get a better idea of what my options are. Don't have any experience with these types of parts

Re: Electrical Gurus - Help me fix this Puch electrical tester

They make new ones every day . Just have to find the correct values .

Deoxit is one of , if not the best electrical cleaners .

Only advice I'd give is go easy . No ham-fistedness needed .

Keep us posted . ;)

Ok wow potentiometers are insanely simple. The knob itself was just frozen from a bit of corrosion but I cleaned it all out with contact cleaner and polished corrosion off and it works like a charm again
