Patches and discussion for Ensoniq VFX family

Hi all,

I'm a french enthousiast user of my VFX since 1989. Never had problem 
with this synth, but today i can't use it more because i need to 
replace some parts of the synth (wich are really dead) :

1. the memory battery (original comes from Matsushita Electric. 
3Volts. Ref : BR2032)

2. the data entry slider (circuit-board mounted, located to the left 
of the display) labelled as "pot2" in schematics. REF : 89175-5KB

3. one pushbutton microswitch, (circuit-board mounted, part used for 
pressing the softs buttons, this is the one used for the up arrow 
button located to the left of the data entry slider)

Please, can you help me. I need to know where to find these parts.

Thanks
Olivier Bouteiller
