stroh modular mirror core vco, kit, motm, 4U

this is a full kit for the j3rk dual mirror core vco for the MOTM format

the kit includes everything required to build the module. You supply wire, solder, and a little thermal paste for the tempco.

included in the kit is the panel, 3 pcb set, all pcb components including the SMT voltage shunt, pots, switches, jacks etc.

this is a moderate to advanced build. there are ~450 pcb components including one SMT part. The build guide will walk through assembly step by step.

the module, as described by the designer, Dustin Stroh:

The VCOs I'm calling "Mirror Core". It's our take on the internals of a CD4046 VCO, only built out using separate components. The CD4046 VCO didn't have high linearity for tracking in mind, so we've improved this significantly. I call it Mirror Core because it uses two opposing sawtooth cores, which is able to generate a perfect 50% square wave. 

One of the more unique features is that we expose a logic level unipolar output, which can be used for clocking and logic purposes. 

Features of the VCO: 

Coarse/Fine tune controls. 
1V/Oct input (high tracking range) 
Linear FM input 
PWM control 
PWM CV input 
VCO/LFO switch 

Saw wave out
