PCB 1:
Populate shortest parts first.

Step 1: 100k Resistors
R1-R4, R20, R21, R27, R28: 100k

Step 2: 499R Resistors
R5 - R19, R22 - R26: 499R

Step 3: beads, diodes
FB1, FB2: 68 Ohm @ 100MHz
D1, D2: 1N4001 (alternate 1N5819)

Step 4: sockets
optional: 2x 8-pin DIL sockets

Step 5: capacitors
C3 - C6: 100nF (ceramic, MMLC or film type)

PCB 2:

Step 6: resistors
R5, R11, R13, R14, R18, R19, R25, R26: 499Ohms
All resistors on this board are 499R

Step 7: PCB 1 jacks
Place jacks in pcb 1 (green). Do not solder.
Line up faceplate and add nuts to jacks. Finger tighten and once the jacks are straight, solder jacks.
Remove faceplate before step 8.

Step 8: PCB 2 jacks
Place jacks in pcb 2 (blue). Do not solder.
Line up faceplate and add nuts to jacks. Finger tighten and once the jacks are straight, solder jacks.

Place both pcbs into faceplate and tighten nuts fully.


Step 9: backside header
Users may choose to use a ribbon cable or one 6-pin stackable header and one 6-pin male pin header.
Start by connecting the male and female headers together, then insert it between the boards and solder each side.
