Which pot is it on the module.
The pots are from Clarostat, the SP7000 number is the MCI part number for the specification for Clarostat.

5K audio taper.
Ideally, Sfernice/Vishay with 21 detentes because this is your channel gain pot and you don't want it to move really.

Vishay are a European company.
Soundcraft/DDA used them as did Raindirk. Neve still do.

Has anyone on the forum successfully ordered replacement Vishay pan and/or channel level pots? I'm interested in getting some of each but not sure exactly how to spec them...

The Vishay pots will not be PCB replacements directly, although they are similar.

Which panpots. The main 2Mix, do you want centre detente? Y/N?

the main 2 mix pan pots - ideally with detentes. As long as I can make them work (are we talking flying leads?) different is okay

I also need the channel level pots, non-stepped

thanks! Really appreciate all your help on this forum!

If you want replacement channel pots as is, then go to State Electronics, ie, Clarostat. They will make 50 off of the same thing. You could give them the MCI SP # and they will probably be able to work out what it is.

If your console does not have detentes at the moment, ie the older version, the detented pots will not fit the PCB, because the size is slightly different, to accommodate the "detente" bit of the pot.
So the pan pot with detente being fitted into a non-detented board will be flying leads, with the pot mounted on the front panel with nut(s).

Give me a day or two and I'll work out the spec(s).

I've got a 618 with 8 detented pans and 10 without so looks like I'll be doing some lead flying!
