CONNECTOR BOARD
Let's start with the connector board PCB. Before you start soldering, take your time and find all the
resistors values
u sing a multimeter
Now insert and solder 2 1 resistors (7x 10k, 14x 1k). Then snip the leads as close to the PCB as you
can (be sure to make this step on all remaining leads in the course of this guide).
Next insert seven j acks and seven green LEDs. Be careful to put the longer lead of LEDs into the
plus (+) hole . Jacks must sit flat on the board, otherwise they will not come easy through the front
panel. D o not solder anything yet .

Turn around the PCB and insert s even

orientation! Flat side of transistors must
match the outline drawn on the PCB. You may
also want to push the leads in the upper part
closer to each other to insert the transistors
closer to the PCB (although they should not
be flat with the PCB).
