Take your time now and relax for a while. Then do the last

double check of all soldered joints at this

point

. After next steps it would be

MUCH HARDER

to do any repairment.

Don’t forget to place the

ICs

into the sockets (2x; Attiny85). 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.
