Vintage Synth Repair

Hello, 

I hope someone can help.

I'm in search of new replacement RESISTOR TRIM POTS for my Micromoog.
(example 1K, 10K, 100K, etc).

I have had problems tuning it and someone suggested to me a
while back (by e-mail)that replacing the trim pots should help.
I was suggested to order from some "standard" online electornics 
supply store...but I forgot the name of the place.

The trim pots are the ones mounted on main board and are about 
10mm x 10mm in size with a plastic tuning wheel plus 4 circuit 
board mounting pins. 


Any ideas?

Hi Allan

 

If these are similar to those used in the Minimoog then you can find
replacements within the RS Components catalogue.

Thanks for replies! 


The closest examples I can find are:

Mouser

All the above have 2 or 3 pins. The pots in the Micromoog have 4 pins.
However, 1 or 2 appear to be for mounting. I noticed some pins are
soldered to pads that are not part of circuit... My guess is I can 
make the above examples work as long as the specs are same 
and the correct pins can be attached to board...

Are the Minimoog type similar to above examples?

Hi Allan,

Here�s the mailadress: mbucki@...

This guy is sitting on the old Moog stuff, he bought all the old original parts from moog.

Best regards

No!  The ones in the Minimoog are similar to this one:

Digikey is one place to look.  Jameco is not so much oriented toward
components as Digikey, but AFAIK, they do deal in them to some extent.
