Feague - NLC - Build notes

These are my build noted for the Nonlinearcircuits Feague module.
It's a 4 pole filter and Quadrature oscillator in Eurorack format.

Andrew's build notes are here:

A Quadrature oscillator is a phase shift oscillator.
 It uses an op amp integrator to obtain a full 90° phase shift.

 Here is a simplified circuit to demonstrate the principle.

The virgin PCB:

Get those ICs on first.
Trannies on next:

Some NLC words of wisdom:
Monday Morning Gunk.

Resistor RL - for LEDs. I'm using 470R.
Resistors marked with a "C" = 100K

To be continued ... waiting for parts.
