Description

NEARLY Full DIY Kit. You just provide the VTL5C3/2 Vactrols, tools, time and solder.

Please note we are not providing a Thonk build document for this build, but it’s a simple enough build with no wiring and the Fonitronik documentation is very good.

What we have here is basically a module combining three bandpass filters (vactrol based filter core from the PS3100) with a simple resetable LFO and some clever CV and signal routing.

The module provides
– 3 single audio inputs + a common audio input,
– 3 single audio outputs + sum audio output
– 3 single CV inputs with attenuators + a common CV input
– LFO output, LFO reset input

PLEASE NOTE – The BOM calls for six TL072 IC’s, Matthias Fonitronik has suggested that we ship with five TL072’s and put an NE5532 in position IC4.

The LFO is normalled to the common CV input, which is normalled to the 3 single CV inputs. the 3rd CV channel can be inverted.
