<DIV style="FONT: 10pt arial"><B>Subject:</B> [sdiy] Ray Wilson's SV VCF with
+-15V</DIV>
<DIV><BR></DIV>Hi you all!! I recently finished this module from Ray's
site using my +-15V PSU. I seems to work but the ranges of the pots are too
extreme. It starts to oscillate as soon as I start moving the resonance pot,
and also i cover the entire CutOff freq range near the center position of the
COff pot. Can anybody help me figuring out what values to change so the
response is like the +-12V version?. Or maybe it's simpler to use a couple of
voltage regulators to get +-12V??. Thanks!!! </BLOCKQUOTE></BODY></HTML>
