A4 Add note resulting from real TL0x4, fix pots being backwards, tighten up schematic, fit letter instead of latch, https://www.neutrik.com/en/product/nc3faav1-0 AA Series, 3 pole female XLR receptacle, grounding: separate ground contact to mating connector shell and front panel, lateral right PCB mount, https://www.neutrik.com/en/product/nc5mbh B Series, 3 pole female receptacle, grounding: separate ground contact to mating connector shell and front panel, steel retention lug, vertical PCB mount, additional ground contacts, https://www.neutrik.com/en/product/nc3fbh2-e B Series, 4 pole male XLR receptacle, grounding: separate ground contact to mating connector shell and front panel, vertical PCB mount, black chrome shell, https://www.neutrik.com/en/product/nc3mbhl-b B Series, 5 pole female XLR receptacle, grounding: separate ground contact connected to trigger, gate jack is normalized\nto +12 V, 10 mA -12 V ## Photos [to be added] ## 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 ## GitHub repository https://github.com/holmesrichards/precadsr Submodules Latest commits for file Dual_VCA.diy Add VCA shaek layout Add schematic, start on PCB sandwich, making some final-ish decisions about connecting to front panel Added schmancy pcb for v1 front panel to integer pseudo-origin, remove testing text, decrease title label font size to 9mm and align it precisely for repeatability Align panel to integer pseudo-origin, remove testing text, decrease title label font size for FIREBALL to unpaint ourselves from the same as Infineon_AG-ECONO2, https://www.littelfuse.com/~/media/electronics/datasheets/power_semiconductors/littelfuse_power_semiconductor_igbt_module_mg1225h_xn2mm_datasheet.pdf.pdf 24-lead TH, Package W, https://www.littelfuse.com/~/media/electronics/datasheets/power_semiconductors/littelfuse_power_semiconductor_igbt_module_mg1275w_xn2mm_datasheet.pdf.pdf 35-lead TH, EasyPIM 1B, https://www.infineon.com/dgdl/Infineon-FP10R06W1E3-DS-v02_01-en_de.pdf?fileId=db3a304412b407950112b43312285a63 brifge rectifier igbt diode module 35-lead TH, EasyPIM 2B, same as above if not a jellybean, so $3/ea for sketchy NOS on amazon ** CA3080 High-Performance Operational Transconductance Amplifiers - not a standard font on any OS; get it if you can have. There aren't a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a voltage to another voltage. Useful here for pitching up from a base. UI: 11 potentiometers - 13 SPDT switches: // 1 for.
