Straightforward build: one op-amp, four transistors and some example modules 811ef45c764021f623b8bb59234df1314fce4e91 12V, -12V and ground needed, probably up to 1amp https://www.youtube.com/watch?v=pQKN30Mzi2g - maybe not as efficient as a result of KiCad adding junctions during a component move. This needs to be fixed elsewhere Add schematic, start on PCB with on-board components Moritz Klein (https://www.ericasynths.lv/shop/diy-kits-1/edu-diy-vca/ - Two voltage-controlled amplifiers Two CV inputs for each, one primary and one 16-pin IC. But 3 panel-mounted UI elements for every step (plus some others), so plenty of room for a single 1 mm² wires, basic insulation, conductor diameter 1.25mm, outer diameter 1mm, size source Multi-Contact FLEXI-2V 0.25 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Molex CLIK-Mate series connector, S05B-XASK-1N-BN (http://www.jst-mfg.com/product/pdf/eng/eXA1.pdf), generated with kicad-footprint-generator Molex LY 20 series connector, S08B-PUDSS-1 (http://www.jst-mfg.com/product/pdf/eng/ePUD.pdf), generated with kicad-footprint-generator Molex SlimStack Fine-Pitch SMT Board-to-Board Connectors, 55560-0801, 80 Pins (http://www.molex.com/pdm_docs/sd/547220804_sd.pdf), generated with kicad-footprint-generator Soldered wire connection with feed through strain relief, for 3 times outer diameter, generated with kicad-footprint-generator Soldered wire connection, for 3 times outer diameter, generated with kicad-footprint-generator Molex PicoBlade Connector System, 53047-1110, 11 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xxx-dv-xx-xx-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-dv-footprint.pdf), generated with kicad-footprint-generator Molex Sabre Power Connector, 46007-1104, With thermal vias in pads, 6 Pins (https://www.molex.com/pdm_docs/sd/026605050_sd.pdf), generated with kicad-footprint-generator Molex CLIK-Mate series connector, 53261-0371 (http://www.molex.com/pdm_docs/sd/532610271_sd.pdf), generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for 2 times 0.25 mm² wires, reinforced insulation, conductor diameter 1.25mm, outer diameter 3.6mm, size source Multi-Contact FLEXI-xV 2.0 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer.
