Yusynth Transistor Ladder Filter

Minimoog filter clone PCB

'bridechamber pcb parts kit' is the original 'brown bag' pcb parts kit

synthcube kits includes panel, pcb, brackets, pcb and panel parts, mounting hardware, et al with each component individually bagged and labelled

MOTM 2U panel

this pcb uses 2XMFOS universal mounting brackets to mount to the panel

from yves:

"Well, it was meant to be! I could not possibly avoid building a clone of this very successful and famous filter: the Minimoog VCF!
This filter has a sound of its own that contributed to the success of many songs during the 70s and 80s.

My aim here was to design a quite faithful copy of this mythic filter while using components that minimize the burden of selecting a great number of matched transistors. This is why I used cheap transistor arrays (CA3046). As for all the other filters of my YUSYNTH project, I have added an input and an output buffer to adapt this filter to the input and output levels of my modular system.
Because, my power supply standard is +15/-15V, some values of resistors had to be modified."
