Multi-Band Distortion - NLC Build notes

These are my build notes for the Nonlinearcircuits Multi Band Distortion module.
It's in Eurorack format.
Andrew has based the layout on a Buchla 194 filter.

This is a fixed 4 channel bandpass from the late 1960's.
He has however added some goodies: Some Fuzz circuits & four Korg 3200 VCAs.
The distorted signal can be mixed with the clean signal . The VCAs use vactrols and allow CV control of the mix.

Andrew's build notes are here:

There are some useful links in the NLC blog:

Some pics of the virgin PCB and faceplate first.

Some NLC words of wisdom:

Jack Smith was born on November 14, 1932 in Columbus, Ohio, USA. He was an actor, known for Flaming Creatures (1963), Chumlum (1964) and Scotch Tape (1963). He died on September 25, 1989 in Manhattan, New York, USA.

I like to get the ICs on first.
Then the rest of the SMDs
Now for the rest of the through hole stuff:
resistors, headers, caps, etc

Vactrols next.
The white dot on the vactrol is the cathode.
On the PCB, the cathode is marked "k"

Jacks & Pots. All B100K
And the faceplate.
Another one done. :-)
