Alpha pots: barely enough to navigate fluently in preview mode. * @todo Add a front-panel PCB d40f7ca1ca Experimenting with more panel layout 3bfacc0b86 Add main pdf UI: 11 potentiometers 13 SPDT switches (many used as SPST) 2 momentary pushbutton switches - 1 rotary switch - number of pins: 13; pin pitch: 5.08mm; Angled; threaded flange || order number: 1776524 12A || order number: 1776977 12A || order number: 1924499 16A (HC Generic Phoenix Contact connector footprint for: MC_1,5/10-GF-3.81; number of pins: 11; pin pitch: 7.62mm; Angled; threaded flange || order number.
