I need to replace 2 old, dodgy mini pots in My Washburn B-200. Both are soldered to pre amp board, one is volume, one is a bass control, both are rated A100k. They look like pan pots to me but have no centre detent. Do any of the electronics boffins know where I can get hold of any like this?

 

Cheers,

James.

Looks like the 2 100k pots are bridged (soldered together) on the board, giving them an impedance of 50k - you could either use a dual gang 100k, or a mono 50k. The taper would be different on the 50k mono pit though, so best stick with the dual gang 100k.

Here is a shot of the whole thing. maybe this will help?

 

As my electronics knowledge is pretty weak at best, not sure what AC or MN is?

 

The tone pot is a replacement I put in, it certainly behaves like a treble cut and boost. It goes from EB-3 to Mark King slappity tap in about 2 seconds!

I don't get why the taper would be different ? Apart from errors due to track accuracy - but that's not really a 'taper'.

I might be missing something !
