220k Treble Pot - broken

Postby nwjr » Fri Mar 16, 2018 4:51 pm

Hello, anyone know what the effect of swapping a 220k treble pot for a 200k? The stem on mine fell out, the resistance measures 1.4M and i get no sound. Assuming its this pot? I ordered a new one but they sent me 200k, think it will work?

thanks
Nicholas

Well I replaced it, I've got sound again but just not any volume - this amp used to be LOUD. I tried a spare set of pots. Would this VR effect volume?

How did you measure the resistance of the pot? Measure the two outside terminals. You may need to make sure it's out of the circuit by lifting the wire at one end. If it's really a 220k pot then 200k should do. You can check the outside of the pot itself to see how it's marked. When this pot broke it may have become "open" electrically. Did this amp work before this pot broke or is this amp new to you?
