Steiner-Parker Microcon - Euro module - Build notes

These are my build notes for the Steiner MicroCon (Eurorack format).
The original Microcon was a full voice module.
It's very rare & was first produced between 1977 & 79 as a complete synthesizer in a single module with its own power supply less keyboard. It has its own LFO, Filter, EG & VCO.
The original module measured 4 x 6 inches.

I purchased this modern eurorack kit from SynthCube.
The circuit/PCB was recast by David Ingebretsen in 2012, with permission from Nyle Steiner.

The euro format panel is designed by Clarke Robinson and produced by synthCube.

It might me fun to install the PCB in a box of the same dimensions as a homage to the original
module, though for the moment, I'll keep this in Eurorack format.

 

Install the resistors first.
There are 10 Diodes - Switching vR/100V Io/150mA (standard 1N4148)
And two 1n4001 Rectifiers (Vr/50V Io/1A T/R)

Headers & caps next.

The two trimmers and that tempco .... needs to be in contact with the IC.(SSM2210).
It's a dual matched transistor.

The Microcon uses two vactrols : VTL5C3/2. These are the same type used in my Buchla.

The original BOM uses a 74c14n Inverter - It's a Schmitt trigger.
This part is obsolete and has been replaced with a CD40106.

It's time to wire everything up.
