Studer Revox poti knobs and fader caps

[classic86]

Hi Everyone,

I‘m looking for poti knobs, poti caps and fader caps for Studer A779 / Revox C279 / Revox MR8. After a search on the web I have the impression there is no source for original spare parts.
Does anybody of you have something available? Part numbers are for example 1.775.370.31 and .32

Thanks!
