From the project
KOSMO Version of the Kassutronics Transistor Ladderfilter
A Kosmo version of the Kassutronics transistor ladder filter.
Find the documentation and BOM here: (https://github.com/kassu/kassutronics/tree/master/documentation/Transistor%20Ladder%20Filter)
You need to match the transistors, which is a bit boring. Those that I got where already pretty close (within the recommended 2mV limit), but some outliers, so maaaybe you could just try without matching.
