Gain pot for Marshall 4211 combo

robinbowes

I'm looking for a replacement gain pot for a Marshall 4211 (combo version of 2210).

Its a dual 1M LOG pcb mount with a splined split shaft.

Anyone know a source?

Got a response from Marshall:

That will be too small - the stock part is a full-size pot (23/24mm). It may be easier to get a plain shaft one and replace the knob with a grub-screw type. (You *can* still get these from Marshall.)

It's unfortunate that Marshall won't supply internal parts to non-approved techs now, but it's probably for legal reasons.

Yeah, the linked one is too small (thanks for the thought @mooncat ).

I'm currently seeing what certification they require to be "approved". If that comes to nothing, I'll see if I can get a friendly local tech to order a part for me.

Cheers,
