NLC - CellF Voice - Build notes

I've had this PCB/panel for 4 years... finally getting around to building this.

I finished the companion to this about a year ago, the CellF action.

These two panels were developed for the cellF neural synth project where a synthesizer was made to be controlled by live human neuron cells.

Some pics of the virgin PCBs

The CellF action build uses smd resistors, caps & ICs.
All transistors are thru-hole. 

 

The PCB is very large 

Each board has. 
2 tri-core VCOs 
2 LFOs 
2 LPGs 
3 VCAs 
VC spring reverb 
diff-rectifier 
jerkoff chaos 
2 281 EGs 
Sauce of Unce. 
Pots and sockets mount on PCB, no wiring (except to reverb tank). 

I'm building version 2.0  

 I usually put on the ICs first, as these are the most fiddly.

Regarding the NJM13700 .

I'm using   regular LM13700 SOIC . they will fit (in addition to some NJM13700s)
These are transconductance amplifiers.

I'm using 470 ohm resistors for the LED resistors (RL)

There are 2 CMOS chips used in the build: 4001 & 4066

Using these 10V zeiners

The 10V voltage regulator: 7810

JFETS: using J112 x 4

Vactrols:
Using 2 types:

The single vactrol NSL. the white dot marks the cathode.

VTL 5c3/2..... I used them a lot in the buchla "clones"

The sloped edge marks the cathode. The cathode is labeled on the PCB with a K.

The Dual LED has a common Cathode. Its orientation doesn't matter.

Check the led fits in the panel hole before putting it all together. I had a batch of duals that were a bit big and the needed 0.5mm drilled out.

almost there.
Final tests.
