UP and DOWN
Two pot brackets to suit
Leaded or taped ferrite beads
L1, L2
1m of multistrand hook up wire
Two knobs
Two decent quality jack sockets, eg. Switchcraft 112
You may well want to use sockets for the ICs. I would recommend low profile turned pin
types as these are the most reliable. Three 8-pin DILs and one 14-pin DIL are needed.
