[sdiy] Update to Fred's - The tax day edition

[Tim Daugard]

http://home.earthlink.net/~synthfred/h_update.htm

This is the last update for three weeks or so. My son's DIY project was
born yesterday. I have to travel this week, etc.

This edition finishes off the keyers - a voltage controlled attenuator, a
transformerless ring mod and a non-ota VCA.

Enjoy,
