Additional Part Notes
• Capacitors are shown in nanofarads (n or nF) where appropriate. 1000n = 1uF. Many online suppliers do
not use nanofarads, so you'll often have to look for 0.047uF instead of 47n, 0.0056uF instead of 5n6, etc.
• The PCB layout assumes the use of film capacitors with 5mm lead spacing for all values 1nF through
470nF. I prefer
EPCOS box film
• Potentiometers are Alpha 16mm right-angle PCB mount.
• Switches are Taiway (Small Bear) or Mountain Switch (Mouser) brand with solder lugs. I prefer the short-
toggle variety, but that's just a matter of aesthetics.
• I recommend using
the board and prevent shorts. If you don't use these, use some electrical tape or cardboard to act as
insulation. The right-angle pots will make direct contact with the solder pads otherwise.
