Title: Potentiometers of Torii MK3 and CSP2+
Post by EdGuY on 09/10/17 at 10:05:51

is there any idea what these potentiometers are? 2C3 (from Torii 3, bass/treble) and 2G4 (from CSP2+, gain adjustment)? Want to replace them but can’t find any data.

Ohmic law type A or B?

2C3=B50K?

Pop them out, on newer pots it's usually screen printed on the circuit board rather than stamped in the metal like the pots of days past.

You right, I found type markings and replaced all pots. Now I can adjust more precisely for example gain and balance R & L channels when using unmached tubes. 10 clicks attenuator on preamp was not accurate enought at all for that purpose.

I've thought about click adjustments on the bias as well. Just seems like an expensive add-on though.
