Greetings
I have an old amplifier i would like to restore, but i have problems with pot values. The volume pot, which has a tap for loudness, is ok. Bass and treble pots are however bad and i would like to replace them. They have damaged carbon tracks inside, usually i open them up and clean them but i cant for these two.
Here is the tone control circuit and i would like to ask if this circuit could be modified for different values of potentiometers, by that i mean more standard values, beacuse here in slovenia i find it difficult to obtain even a 220 k lin stereo pot, but i simply cannot find a 22k one.
Any suggestions for modification🙂

I cant get your links to work but more to the point volume controls come in all shapes and sizes please post make and model of amplifier first.
Are you saying you don't want to obtain volume controls by post within Europe only locally in Slovenia ?
Farnell (UK) sell 220kohm volume controls .

I assume, you will get such potentiometers only as surplus or in used condition.
