Okay, nevermind, I already fixed this...
The problem was with unstable Chorus LFO oscillation. Not sure about
the exact reason, but I was able to find a quick workaround - adding
10M (yes, weird - it's quite large value) resistor in parallel to C44
completely solved the problem and LFO is stable now (and Chorus works).
So, my Poly-800 is ready for Hawk-800 :-).
Best, Saulius
