9.
If you are using a panel with holes for
the LEDs like the new 2016 version
from Thonk then read all details before
proceeding!
Lift the PCB so the LEDs drop down to
be flush with the surface of the PCB.
Take the front panel and carefully place
over the 4 pots and 8 jacks without
disturbing their connection to the PCB.
Put a couple of nuts and washers on the
pots as shown to hold the panel in place.
Carefully rotate the assembly so it is PCB
side up. Check all the LEDs have
dropped back again and are touching the
front panel and are perpendicular to the
PCB surface.
Now solder all the loose items… that’s 52
solder joints,
double
check you didn’t
miss any
!
Don’t remove paper from the
Acrylic panel before painting!
If you are using a panel with holes
for the LEDs then ensure the LEDs
are pushed through before
soldering. If you are using the flat
top LEDs and want them flush to the
panel then follow the instructions in
the Turing Mk ii document here. Use
masking tape! :

Remove the panel, if the LEDs look a bit
wonky then now is the time to straighten
them up by hand.

pin headers into position as shown.
