[sdiy] serge free radicals

[Anthony Bisset]

hey guys, i'm about complete with the serge rebuild and am wiring power
for all the panels during which i'm testing each module. Anyway my WAD
is acting up (not a new problem, but i'd like to resolve it).

this WAD is putting out HF (~15khz) on the a or b delay channel.  when i
switch the SAD1024's around both A&B outputs go silent.  i have
an extra sad1024, but substing it in as either a or b delay doesn't make
a difference.  I know there was an evening long ago when i was struggling
with consciousness and reversed the +/-12 hookups or maybe it was -12 and
ground, not sure (it was a really fuzzy moment).  Fear had a new smell.
I can't see any visible thermal artifacts.  Anyway, any ideas what i might
have toasted?   While on the topic.  Anyone know any stupid bbd tricks or
clock driver substitutions that result in "interesting effects?

I have tape for analog delays and max/msp for digital.  This bbd
implementation is cool, but so short as to have a limited use during
performances.  Anyway, bends, hacks and suggestions for mods would
be most welcome.  In the absence of any cool hacks i'd like to extend the
range.

Btw, i know there was a discussion about cutting serge panels with hack
saws and what not to modularize them...    We'll I'm happy to report I'm
probably one of those rare people who've dremel'd a serge vca(x3)+rm board
apart into seperate modules.  It was really nasty, had to wear a gas mask.

I keep threatening pictures.. So, that threat is re-iterated here.

easier,
-anthony
