Transistor Ladder Filter

Maker	Kassutronics
Type	Transistor ladder low-pass filter
Mounting	Through-hole
Width	8 HP
License	Proprietary (No licence published)
Difficulty	🌶️ Large through-hole

Clone of Moog transistor ladder filter. Uses the classic transistor ladder core and exponential converter. Moog-inspired but not an exact replica, with an instrumentation-amp output, a CV attenuverter and a Drive control for input saturation. All through-hole, 8 HP.
