Before you begin to move forward, you might want to clean your PCB. You can use e.g. isopropyl
alcohol. Put some of the liquid all over the PCB using the brush (don't let it flow into the pots), let it act
for a while and sweep it off . Then just let it dry. You can repeat these steps until you are satisfied with
the result.

LAST CHECK

Take your time now and relax for a while. Then do the last double check of all soldered joints. After
next steps it would be MUCH HARDER to do any repairment.
INSERT ICs
Don't forget to place the ICs into the sockets. There is a signed notch on each IC that has to match
with the notch on the socket. Be also aware that LFO goes to the socket on the left and VCO to the
right one. Installing ICs can be also a little tricky. You should bend the IC leads in slightly with your
fingers. Then press all the leads into the sockets in one shot.
BATTERY HOLDER + plastic strip & washer
Now place the battery holder to the PCB. Watch out for the orientation!
