Spring Reverb Mk ii

Eurorack DIY Kit
Instructions

33.
In order to fit the top flat face of the
LED flush with the panel we
recommend using masking tape to
hold its position before soldering.
You can now solder all pots, jacks
the LED and the switch. Don’t miss
any joints! Remove the panel again
when you are done.
34.
Go back to the IC packet and find
the two
TL074CN
and the single
NE5532P
and position as shown on
the
BACK PCB
NOTE
– Orientation is vital! Make
sure the notches in the ICs match
the notches on the PCB silkscreen.
NOTE
!
You will need to bend the
pins on the IC inwards slightly so
they are at 90 degrees to the body
of the chip. They will come slightly
splayed out. This can be done
safely by clasping the 4 pins in a
pair of pliers (not the cutting edge
near the pivot joint though!) and
very
gently
bending
inwards
together. Repeat for the other side.
35.
Take the final two TL072CP ICs and
position as shown on the
FRONT
PCB
, the circle on the face should
be at the notch end of the socket.

– Orientation is vital!
