Hello all, I have an older amp MG15CDR. Bit of a problem with it. Crackles when you turn the gain pot or the tone pot. Seems to be worse when just turned on.  Maybe it's the potentiometers need replacing? Anyone else had this problem?  I can't see that Marshall will supply just these parts.

I would like to repair it, as it is a great little amp, suits my needs well.

I think all you need is to spray CRC QC Contact Cleaner into the pot and move the pot back and fourth for about a minute and let it sit, then try it and see if it still crackles - James Lingerfelt 17 Jan 2022 at 07:48 PM

Hi Peter,

If you contact, they can arrange to have it repaired at the factory.
