Just picked up a DS2 - mostly works  - the main issues are really low
output on the main outs and noisy output on the headphones.

Looking at the schematics I notice two 3046 chips in the design, but
my DS2 has two 3086 chips. Any idea if there is a diference between
the two? 

peace,

Hi.  I have a DS-1 which I got off eBay which I have mostly fixed up,  
but I still have one issue.

Oscillator 2 will not stay in tune.  It warbles up and down.  I  
thought it was just a bad pitch pot, but it wavers even when the dial  
is being left alone.  It never settles down.  Where should I be looking?
