Integration
Mount the back panel onto board using two #6 screws into the ac connector.
Mount the side extrusions using #4 screws. They act as card guides for the circuit
board.
Set headphone jacks in place, washers removed. Apply volume pot washer.
Carefully mount front panel, securing in place with volume pot nut. Add nuts to
phone jacks, but loosely.
Solder one pin on each phone jack. Not with one finger pushing jack down into
place on circuit board, heat up the soldered pin with soldering iron. Jack should
not push down into proper position, flat on the circuit board. Do this to both
sides. Solder remaining pins.
