sunn beta lead reverb pots?

[deadmeat13]

hi.
I'm in the process of restoring a betalead (first time restoration) and the potentiometers with four pins are throwing me off. i've got the parts list it says 30K s Curve but I'm not turning up anything in a search. the four point pots are on the level, reverb, and master volume, although i'm not sure if they are the same ohms and whatnot. also, i believe all the others are 100k but the drive pots are 1 meg blue case and 1 meg metal case. can these be replaced with an Alpha Dual 1 ma pot?
thanks for your time, and sorry to be a newbie dummy,
mike

p.s.
also if you guys could point me to the best parts dealers that would also be helpful.
thanks!

First off, do you have a schematic and BOM?

An email to don.moose at sbcglobal.net will get you one.

S-curve pots and 4-pin pots are custom-order items (minimum quantites in the thousands). Search for threads about pot curve and pot taper - you might be able to get close with a couple of resistors across the legs of a more typical pot ... maybe.

Hope this helps!
