Serge TKB build notes - 10 - Wiring the Faceplate to PCB

***Click here for the Index of the TKB Build *** 

We are almost there.:-)

We need to make the final connections between the Faceplate and the PCB.
This is the guide:

What do these numbers & letters stand for ? (from left to right):
G – VERT CLOCK
7 – ABCD OUT
3 – A OUT
4 – B OUT
5 – C OUT
6 – D OUT
8 – KV
P – KEYBOARD PULSE
V – PRESSURE
K – RESET
L  – RESET
J – RANDOM SELECT
2 – ON/OFF Switch (Tab closest to panel edge)
N – CLOCK
H – HOLD
M – UP/DOWN
--------------------------------------------
The 4 pot boards also need to be wired to the PCB
 9 – A POTS
10 – B POTS
11 – C POTS
12 – D POTS
--------------------------------------------
17 – LED RETURN

This is how you connected in the 1970s.
I've circled in red  connections 11 & 12 to C & D pots

I'm connecting the A,B,C,D pots from here on the modern TKB:

Almost home. 

Just need to connect # 17 ... the LED RETURN
