Hello everybody, this is  my first post here:

I want to put a Monotron in a new housing with CV-ins and proper in- / output jacks. i will need new potis as well.

And that´s my problem:

Does anybody of you know which Potis I need? I want to replace the volume wheel and the trim pot at the backside as well. So any information about this will be helpful for me.

thanks in advance!

Have a look at the Monotron circuit - it'll give you all the values.
If at first you don't succeed, stick it through a fuzzbox.

Hmmm....   looks like every pot on the board is 10K except VR1.. it looks like it's 100K

10K Log don't forget, otherwise the controls will be all up one end.

Just about everywhere in the world, A taper pots are linear and B is logarithmic.  The US has to be different though, and has B for linear and A for log.  If you're unsure, look for a volume control - they're pretty much always log.

VR1 is 100 ohms.  Is it actually broken out to the panel, or is it just an internal scale tuning pot?
