lugs haven't slipped out of their holes. Gently tighten each pot nut making sure you do not over
tighten or scratch the panel's front surface. Now fit and tighten the switch nuts. If you chose not to
solder the switches before fitting the panel, once the switches are secured with their nut, you can
now solder their leads.
With the pot/switch board in place you can solder the LED's two leads. For my builds I used a flat
topped LED and soldered it so that the flat top was aligned with the top surface of the panel. If
using a flat topped LED you can use a bit of sticky tape to hold the LED flush with the surface
while you solder.
Now attach the socket board making sure it is the right way up. The board is mounted so SK1 and
SK11, fit into the panel holes for Key CV and Gate respectively. Fit a dress washer and nut for each
socket on the outer surface of the panel.
Now we need to fit another M3 spacer, this time it's on the main board which will eventually secure
the VCO board. Like the pot/switch board this spacer will be sticking away from the panel but this
time it's fitted to the top side of the board. It is secured on the underside by a 6mm M3 screw, M3
toothed washer, and M3 flat washer. Again, it's worth checking that the VCO Board will fit
comfortably into place. If it does then take off the VCO board and put it aside for now. It's time to
fit the main board to the pot/switch board properly.
The single M3 spacer needed to secure the VCO board in place.
With the module face down fit an M3 flat washer onto each of the threaded studs on the spaced
secured to the pot board. This prevents the boards from being pulled closer together than the SIL
headers would like – a 12mm spacer is a little too big, but 11mm with a flat washer is perfect.
Now fit the main board to the pot/switch board. Make sure that all the SIL headers and sockets are
aligning correctly and no pins are out of place. Secure the two boards with a flat washer, an internal
toothed washer and an M3 nut on each threaded stud.
The VCO Board can now be fitted and secured in the usual manner.
