Piece display PCB

Post by Tony »

For this you will need the entire contents of BAG 4 plus solder from BAG 5.

230x Diodes - Copper-orange glass cylinders with a black band marking one end. These are polarised and must face the same way as in the photographs.

Capacitors - Brown ceramic discs. Seven of these are used on each board.

Capacitors - Green rectangles. One of these is used on each board.

Coils - Black plastic sleeved ceramic-like material. One of these is used on each board.

Finally, the prewound inductor. You'll need to carefully remove the protective plastc sleeve from it first.

Use one of the paxolin base covers to make sure it's at the right depth through the hole in the PCB. You want it to be just level with the bottom of the base cover.

Dismantle the three 25 way 'D' sockets, the easiest way is to cut through one of the rivets then seperate the two halves of the shell.

Open up the socket housing and remove the pins.
