Prophet 600 out of tune?

2002-03-26 by Brian Andrew Marek

Okay, so I got the Prophet 600 working (changed out the Z-80 - easy!),
but now I'm finding another problem.  Apparently one or more of the
oscillators are out of tune, even after doing the auto-tune thingie on
the board.  What could be causing this, and how would one remedy it?

Thanks

BaM
