Vortex problems...

[Olivier Malhomme <malhomme@infobiogen.fr>]

Thanks for the explanations. Maybe i'll have to unscrew the unit... I
could have a spare pot of the machine, only i'm not so easy with it. I
don't dare too much taking the solder into it to replace the pot. I know
that if I have statics on the bench, I may kill my unit, and i don't know
how to remove statics when running the solder thing. I don't even know if
yoy can access the thing. And yes, I step on the idea of having th emchine
for 150$ (in fact with shipping it was 234$) wich is anyway less than the
equivalent of 550 bucks of the unit here (would you believe it!). That is
the deal: half the price, half the presets....
