Cgs synth

hi Dave

> ps- what did you use for your exponential converters?

the first one has a LM394.
the 2nd got a 2SC1583 (the shop selling 394's went belly-up, 1583's
are starting to dry up too)
it works fine, but i'd like to find some more LM394 or MAT-02 for the
next two.
The tempcos were tiny little things, size of 1/8W resistors, got them
from a friend.

btw - i regularly check out your homepage. love your work.
cheers
andrew
