VCFs for the audio-range caps, and polyester film for the LFO-range caps.
These seem to work very well. Typically, I use 390pF in VCOs and 220pF in
VCFs for audio-range, and 100x that for LFO range.</FONT></SPAN></DIV><BR>

<DIV>I don't think it's a question of through-hole vs SMD. It's more like
ceramics vs something else (film, in this case). It *is* interesting, though.
Behri never advertised this capacitor change AFAIK, so I wonder if maybe they
just weren't entirely sure which to use yet. Personally, I've never found a
filter where yellow, box/film sounded better than C0Gs. If I decide it's worth
voiding the warranty, I would try polypropylene in mine, if only because it's an
easy change.<BR></DIV></DIV><BR>
