hi all,
I've put up schematics for the circuit I'll be using for the PT2395
delay. This is the best I have gotten it to sound.
http://www.sdiy.org/destrukto/vc_delay.pdf
A few notes: This isn't fully tested. The VCA, and input/output/mixer
opamp sections (pg.2) are a little different than the version I built.
It should work though because the VCA is pretty much the ASM-1 VCA. I
switched to this VCA because it requires less parts than the CA3046 vca
I originally had. The gain resistor (600K) on the vca is probably too
small. If you decide to build it, double check the pins on the
LM337L/LM317L because the schematic shows pin numbers that may lead to
confusion. page 1 of the schematic should be tested and correct
(assuming I didn't make any schematic capture errors).
I'm having a PCB made for it hopefully next week, but I thought some
people may be interested to see the schematics.

now, to start work on a vc-res mod for the steiner filter
