I have to replace some scratchy potentiometers used as volume potentiometers in a Rocktron Velocity 300 guitar power amp from the early 1990's.

These two parts are labelled:

• 15A100K 9252
• TØB10K 9303

Does someone have some informations about them or a source where I can get information?

THX, regards Jörg

Edit: I've found schematics for the Velocity 300:
