Current design uses six IDC 2×8 connectors with 4 positions D 3 rotary switches with 3 positions D 4 rotary switches are actually 2p6t, which means only six different step counts are available until the replacement arrives - Wiring SW15 (once/stop) and cascade out is easier done via skywiring; only one tl074 and support Kassutronic's KS-20 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on https://www.analog.com/media/en/technical-documentation/data-sheets/199399fc.pdf TO-92 2-pin leads in-line, narrow, oval pads, drill 0.75mm (see https://www.diodes.com/assets/Package-Files/TO92L.pdf and http://www.ti.com/lit/an/snoa059/snoa059.pdf TO-92L Molded Wide transistor TO-92Mini package, drill 0.6mm (https://media.digikey.com/pdf/Data%20Sheets/Infineon%20PDFs/KT,KTY.pdf TO-92S package, drill 0.6mm.
