Patches and discussion for Ensoniq VFX family

You guyz seem to have all the answers :) Here's another question for 
you: my VXF-SD seems to be overheating - at least the heat sink gets 
extremely hot within 20 minutes of powering up. And unless I'm 
mistaken, this is causing a fluctuation in the tuning. Is there a 
known fix for this or is it a 'fan & ice' situation? Thanks in 
advance.
