Yamaha G50 112/2

I have a Yamaha G50 112/2 with all three pots on the parametric EQ broken or bad. a parts list or schematic would help me ID the needed parts. Any help would be greatly appreciated.

Thanks to Vintagekiki the schematic can be found here

The 3 pots are:-
Level = C 50k with tap! 50k Log
Q (width of skirt) = A 50k (lin)
Freq. = C50k double gang (log)

If you can clean or repair the pots , that might be your best shot, as they may be difficult to obtain particularly the level with a tap from the track!
I presume this is the old system for Log and Lin taper i.e. C = Log (audio taper) and A = Linear taper.

If the shaft is broken perhaps you can replace another pot on the chassis that is a readily available type -
then swap the track in that pot with the broken one's track.

Caig Fader Lube may be worth buying.

Thanks for the info. The Q pot is completely broken off. The other two are still in tact but at least dirty. I'll try to clean them up. The Q pot is available though. I have a can of Deoxit F5. Do you think that will work?

That will work just fine.
