[sdiy] EML 101 pots

[klosmon]

Hola-
I'm working on restoring a 101.
For a change, most of the circuitry seems ok;  the main problem is that 
this unit appears to have been subjected to moisture over a long period of 
time, and the majority of the sealed Claristat pots are failing.  I opened 
up a couple to see if I could clean them;  large chunks of carbon fell out, 
along with substantial quantities of powder.  Needless to say, cleaning did 
not help them.

The good news is, I've found replacements for most of them;  the glaring 
exception is the "center tapped" pots used in the oscillator waveshape 
selection & filter type selection.  I've never seen these in any of the 
usual catalogs (Digikey, Mouser, etc).

Any pointers as to where I can look?

Thanks.
