Vintage Synth Repair

Hi Simone,
So when you press Osc 2 in the mixer section, the incremental control 
parameter comes up? Does this happen with more than one control? 

In other Moog Source news, I've been working for about a year now on 
a switch panel mod for the aging membrane switches. Basically, I've 
substituted the membrane switches with 'real' pushbutton switches. 
I'll be publishing pictorial step by step instructions on my website 
with all the pin data for the switch matrix, etc. It requires a lot 
of drilling, but atleast you won't have to follow each trace to 
decode it!
