Full kit of the Erica Synths DIY VCO. Has everything you need to build this great sounding VCO.
The original design used the Russian KR198NT1A matched transistor IC. This kit comes with an AS3046 that has identical characteristics as the KR198NT1A. The AS3046 has a mirrored pinout and needs to be mounted on the back side of the main PCB. We have provided a footprint to indicate where the AS3046 should be installed. Of course one can still use the KR198NT1A if desired (not supplied in kit).
This kit also come with extended height socket headers for connecting the two PCBs. These are needed due to the height of the octave switch.
