Hi,
Have a 2204S Marshall 50w head, schematics indicate different pot values for treble pot between 220k-250k. What do you suggest?

I would try to confirm the pot value buy looking at the pot itself. It is always best to get as close as possible to the actual pot value.

This potentiometer is a very close replacement for the broken originals. Same function and appearance.
Excellent replacement for a JCM800 Model 2210 I recently repaired!
It WOULD be nice if there was a link to purchase extra nuts as 2 are required to set each properly.

Perfect fit for marshall replacements but you need to provide a way to buy extra nuts because they are an odd size and you need 2 in order to install them in the amp.
Pot works great!
Just what I needed, ordering and shipping quick and easy
In the picture it show A brass collar coming out of the potentiometer but the ones i got were just an aluminum collar i like things to look authentic and most if not all Marshall amplifiers have a brass collar on there potentiometers
