Now as the last component on this
side, solder in the L7805. Make
sure it’s correctly oriented: The
heat

sink

(metal)

side

should

match the double line of the white
outline on the PCB.

The recommended way to do it is
not to insert the legs into the
PCB holes too far, but just a bit,
solder them in and then bend the
legs at a 90 degree angle as shown
in the picture. This will lower
the depth of the completed module,
so

it

looks

more

tidy.

But

it

shouldn’t

be

necessary

as

most

Eurorack

cases

offer

far

more

depth.

After bending make sure it doesn’t
touch the surface of the MCP6004
!

Now flip the PCB over.

Solder

in

D9

(the

LED)

after

pushing it in all the way, long
leg on the side marked with a plus
sign on the PCB.

Remove the washers from the pots
and

the

outer

nuts

and

washers

from all the switches. Leave the
lower

nuts

on

the

switches

and

lightly tighten them.

Fit all the remaining components
on the PCB without soldering yet.

Now put on the front panel. Add
and lightly tighten the washers of
the 3 pots to hold the panel in
place.

Carefully

flip everything

back over and solder.
