Multimoog help (Osc Problem)

[Philip]

I put this multimoog on the back burner for a year  (infact I swapped
it's ps board with a dud in a frined's micromoog ) but now another owner
has the same problems...by chance has anyone else seen this?

My old email to AH:
>Hi,I'm investigating a problem with my Multimoog. Initially I guessed itwas

I'm Hendrik Krüger (from Germany), and since a month I have exactly the
same probem you had at the end of
1997. Even the current on IC301 is the same.
It seams to me, that it is a typical problem of that synth.
 
I would be verry happy, if you culd remember what the problem was. 
Im also looking for Multimoog schematics, if you know where i can get
them, it would be nice,

Philip
