tube vca
2003-12-06 by osthelder
Hey Ken and group!
I've been playing with the tube VCA and I must say, this is a blast!
I've removed the lowpass cap in the CV circuit and am playing with
high frequency modulation for some non-linear wave mangling.
If you need extra VCA's *and* want to enrich your harmonic output,
this may be the ticket. Of course, it may also force you to enrich
your power supply requirements. Right now, I'm using a separate
triple-output supply (+&-15 and +5vdc)for just the planned triple
tube VCA. This would probably be better done with a separate 5 volt
filament supply and a much larger dual-output supply for the synth's
15 volt requirements. The present method will require me to isolate
my tube VCA grounds from the rest of the synth modules to avoid
ground potential hum. Hmmmmmmm....
Whether I upgrade to a larger dual-output supply or stick with the
present arrangement, I'm going to add tubes to the Engine of Chaos!
It's just too fun to pass on it.
Thanks for letting others copy you homework, Ken!
