Eml synthesizers

I managed to find a handful of genuine A-B centre-tapped pots (various
values) at a local surplus store - grabbed them all! I used to search the
surplus stores out here in NCal for these but only got lucky that one time. 

 

I have come up with some NOS PCB layout pots that have a fourth leg at the
right place for the center-tap (I was jumping for joy that it might be a
real tapped pot until I looked closely). It would make fabricating your own
a bit easier so I bought a handful. Halted (hsc.com) in Sunnyvale still had
some in a bin last time I was there. They're 50k lin but should work in many
applications. The micromoog also uses a couple of tapped pots iirc.

 

Don't rule out opening the pots up a cleaning them out. They are "sealed"
types on the 101 so they may have not been through repeated "cleaning"
attempts. I found that some almost completely dead pots on my 101 came out
fine. Carefully pop a couple of the tabs and flush with cleaner and lube.

 

Good Luck!

Hi,
Does anyone know a place where I can buy 10k center
tapped pots like used in the eml 101?

Thanks,
Regards,

I've never found them anywhere.  On the last two 101s I repaired, I ended up
making my own (getting hold of standard 10k linear pots, taking them apart,
and  using conductive epoxy to cement a center tap to the conductive
element.  It takes some practice, but it is do-able.).
