Eddie, Back in the day, I had my Ensoniq VFX-SD repaired at Al Nalli music in Ann Arbor, MI. The thing started to emanate a 'honking' noise at full scale and come to find out, this was fairly common with the VFX/VFX-SD. Inside, there's an edge connection between two different PCBs and the fix was to hard-wire the two halves together. Here's a page dedicated to them that shows the repair that was done to my axe. http://www.syntaur.com/tech_vfx.html

One thing that they were not well known for was robust mounting of the PCBs inside of the case - even though the case is a beast in and of itself. If your case creaks and squeaks when you pick it up by the ends, it could very well be that some stuff inside just needs to be re-seated, like that edge connector that lives inside.

I'm guessing you have the O.S. diskettes. If not, I can see if I can make a copy (if I can find a 3.5 around here somewhere) and stick it in the mail to you. Let me know via PM.
