Killer resonant analog low pass filter!

The one and only JP8 VCF, 2-pole (12 dB/oct) or 4-pole (24 dB/oct) plus High Pass Filter.

Some highlights of this module are:
- AS3109D and AS662A, ALFA RPAR modern identical to the original IC clones
- High Pass Filter made with AS662A
- WIMA polypropylene capacitors
- selected 2SK30ATM-GR N-channel J-Fet transistor
- two mixed signal inputs
- independent outputs for 2-pole, 4-pole and an alternate output with selection of modes from a switch

This module is a collaboration between Feedback Modules and CMS-LAB.
