Now plug in and test your module.
Refer to the manual if needed.

If something’s not right, it may
be best to unplug the module from
Eurorack power immediately so as
not to damage the PSU.

Most problems can easily be fixed
by reheating all solder joints so
the

solder

can

reflow.

Also

visually inspect joints and see if
you

can

spot

accidental

solder

bridges.

When

everything

is

working

correctly,

you

can

add

the

remaining

washers

and

tighten

them. If using a wrench or pliers,
be

careful

not

to

scratch

the

front panel surface.

As the final step, put the knobs
on the pot shafts.

If you need help troubleshooting or want to share photos, audio and/or
video

of

your

creations

(please

do),
