Capacitor (C13) is connected to trigger, gate jack is normalized\nto +12 V, 10 mA -12 V ## Photos ### Photos ## Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md) How to use 7.5mm holes, not 6mm alpha pots - 9.8mm, +2mm rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm? Alpha pots: tight, only 1/2 turn for nut 11mm - rotary, SR2511 style, with very large range of in-tune response, but comments discuss potential fixes, maybe worth it for a single 1 mm² wires, basic insulation, conductor diameter 0.48mm, outer diameter 2.3mm, size source Multi-Contact FLEXI-E 1.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times 0.1 mm² wires, basic insulation, conductor diameter 1.25mm, outer diameter 3mm, see , script-generated with , script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_WAGO THT Terminal Block TE 282834-5 pitch 2.54mm length 5.2mm diameter 2.7mm Diode, A-405 series, Axial, Horizontal, pin pitch=35mm, , length*diameter=30*18mm^2, Electrolytic Capacitor, , http://www.vishay.com/docs/28342/058059pll-si.pdf CP Radial series Radial pin pitch 41mm length 34.5mm diameter 20mm Electrolytic Capacitor CP, Axial series, Axial, Vertical, pin pitch=7.62mm, , length*diameter=11*4.5mm^2, Fastron, MECC, http://www.fastrongroup.com/image-show/21/MECC.pdf?type=Complete-DataSheet&productType=series Inductor Axial series Axial Vertical pin pitch 55.88mm 11W length 50mm width 9mm height 9mm Resistor, Axial_DIN0922 series, Axial, Horizontal, pin pitch=75mm, , length*diameter=67*35.0mm^2, Electrolytic Capacitor, , http://www.vishay.com/docs/28325/021asm.pdf CP Axial series Axial Horizontal pin pitch 3.81mm length 7.6mm diameter 3.6mm Resistor, Axial_DIN0411 series, Axial, Horizontal, pin pitch=11.4mm, 1W, length*width=12.4*4.8mm^2, https://www.bourns.com/pdfs/PWR4412-2S.pdf Resistor Bare_Metal_Element series Bare Metal Strip Wire Horizontal pin pitch 7.10mm length 16.8mm width 9.2mm Capacitor C, Rect series, Radial, pin pitch=10.00mm, , diameter=25mm, Electrolytic Capacitor, , http://www.vishay.com/docs/42037/53d.pdf CP Axial series Axial Horizontal pin pitch 2.50mm diameter 5mm Electrolytic Capacitor CP, Radial series, Radial, pin pitch=5.00mm, , diameter=12.0mm, Neosid, SD12, style3, http://www.neosid.de/produktblaetter/neosid_Festinduktivitaet_Sd12.pdf.
