Well it always nice to reply your own mail: > Cutoff is bit different.

In theory that would be a problem. Can't say more. I'd > toss in resistor inbetween pot wiper and chip input, 1k or so. > Haven't tried it. Now, if you look at the borad you'll see silkscreened > short link for bypassing trimpot to +V. Hmm, so maybe it really works. > You might even not need 470ohm res he suggested. I got it right except that additional resistor is already there (22k) so Atom's mod is quite right. It'll work no problemo. That 470-510 ohm res is there to put cutoff in useable range. So this looks just OK... Have fun... -- marjan me : Marjan Urekar e-mail: urekar.m@... s-diy : http://surf.to/marjansystems music : http://go.to/forcemajeure
