but I think this is too expensive for a simple pot , isn't it ?

You can either search until you find the right parts or pay retail. I gave you a link and a PDF so YOU can measure the pin and brace placement and find the right substitute.

 

A while back I acquired a Fender practice amp, unfortunately the previous owner hadn't treated it well - I was looking into buying replacement pots, and getting well into the realisation that it would be cheaper to buy another s/hand amp, when on the way to visit a relative, I found an amp just laying under the hedge alongside the footpath. Not as good as the fender could have been and even google had never heard of that brand, but all it needed was a squirt of switch cleaner on the input jack.

Didn't actually get what you're saying . Should I try the contact cleaner solution?

I am sorry, didn't see the pdf .Let me check this and I will post back

 

The pots appear to be made by/for Korg.

Amplified Parts has them for US$4.95. Amp Repair Parts for $7.95 - yikes but at least some more info. Guitar Parts has a big listing of pots for Marshall.

Amazon has a nice picture and some manufacturer info. From the big picture, you might be able to shoot some cleaner into the holes on the side where the resin substrate tabs poke through the metal housing. I use PureTronics 3600 Extra-Strength on my various guitar and amp pots with no issues so far.

Once you get the Korg specs (taper, etc) you can use #12's Mouser link to perhaps source an alternate.

Good luck!

 

Funny, but not true. My 1977 Onkyo audio amplifier is ready for its third squirt job at 38 years old.

In every band I worked with, I was the one elected to do maintenance and repairs.
Guitars and amps.

Not long ago, I tore apart an old Marshall (1972), and cleaned every pot.

If you look around with a mag glass, there is usually a small opening to spray the Deoxit.

That job, took me around 3 hours until re-assembly, and he was pleased as punch.

I was saying the cost of replacing all the pots could be more than a good S/hand amp.

I got lucky and found one dumped under a hedge that was easier to fix than the one I bought.
