Need help to identify potentiometers, please

[softmonaut]

Hi,

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 parts are labeled

15A100K 9252 and
TØB10K 9303

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

THX, regards
Jörg

I think the value are 100K and 10K. You can bring that potentiometers at the electronics shop near you.

Not necessarily.  These are slide pots I believe.

I use "contact cleaner" to fix scratchy sounding pots. Sometimes a coupling capacitor leaks DC current into a pot that makes a scratchy sound that is fixed by replacing the capacitor.

lacquer thinner will be used too.

Lacquer thinner will probably dissolve plastic parts in a pot and deposit it as a mess all over the resistive track.
My contact cleaner is "safe on plastics, leaves behind zero residue and is fast drying". Why not use it?

I saw on E-Bay a lot of pots for guitars electric ect. Punch into top 100k, 10k and view them like I did while looking for 250k Alps
