Instructions
Version 1
40.
Now place but DON’T SOLDER
the button, four jacks, SD card
holder, and two pots as shown.
Thonk kits may include either D-
Shaft or T18 shaft pots.
Remember!
Orientation is vital
for the switch button – make
sure the flat edge matches the
PCB silkscreen as shown.
41.
Now carefully place on the front
panel and screw the nuts and
washers onto the pots and jacks
to secure them in place.
Then use some masking tape to
hold the switch and SD card
holder in place – flat to the PCB
surface.
Once everything is held securely
you can then solder the parts to
the PCB.
NOTE!
Do not use regular tape as it will
leave a sticky residue on the panel –
only use masking or non-stick tape to
hold the parts in place.
NOTE:
The SD card holder has very fine
pins - be slow and patient when placing
and soldering this part in.
42.
Now remove the front panel and
locate the long male pin header.
Break the header into two
lengths:
1 x 11 pin length
1 x 7 pin length
Place these on the opposite side
of the PCB from the rest of the
components as shown, then
solder them in place.
NOTE:
the pins should be soldered flush
and perpendicular to the PCB surface.
