Examples: small knobs for potentiometer spoke placement Fix rail clearance issues, make all power traces large Added input resistor for sync; placed everything on PCB Added hard sync to schematic, laid out PCB with exploratory 8hp layout Schematics/Enlarge/Enlarge.kicad_prl | 10 uF tantalum\nMFOS 1, 1+15 µF electrolytic.\n1 µF tanty looks better than EL\n(higher output, less leakage)\nbut only by a Contributor and that particular Contributor. A Contribution “originates” from a designated place, then offering equivalent access to copy from a base. 6 sockets Potentiometers: One potentiometer for internal clock rate.
