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.
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.
Muffs has a very useful thread here:
David's L's Microcon post is here:
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.
There are 10 Diodes - Switching vR/100V Io/150mA (standard 1N4148)
And two 1n4001 Rectifiers (Vr/50V Io/1A T/R)
The two trimmers and that tempco .... needs to be in contact with the IC.(SSM2210).
It's a dual matched transistor.
The original BOM uses a 74c14n Inverter - It's a Schmitt trigger.
This part is obsolete and has been replaced with a CD40106.
