I recommend plastic shrouded sockets for both the audio, CV and power sockets. This will
reduce the risk of earth loops.

You will also need a power source of some kind. The recommended supply is a wall-wart
supplying 15V AC at 300mA minimum. See later for more information.
A small amount of insulated multistrand wire is needed. This will be used to connect the
sockets and power supply to the board.
IC sockets are to be recommended, especially if this is your first electronics project. You need
eight 8-pin DIL sockets, and six 14-pin DIL sockets. Choose 'turned pin' or 'dual wipe'
types.
