To clone: schematic start, and some example modules main 5a4e89eea6 Add position for resistor between coarse and +12V, value unknown c5e8dbdd1f Align panel to integer pseudo-origin, remove testing text, decrease title label font size to letter for schematic for easier printing

  • Add note that C12 is optional; not needed if using real TL0x4, fix pots being backwards, tighten up schematic, fit letter.
