Step 25

IC2
LM324
Step 26
Cut off the small metal tab sticking out on the potentiometers. Use a cheap plier/nipper for this
step, save your expensive ones for other tasks. Mount 1 washer and 1 nut on each
potentiometer. Make sure the nuts are tight. Sometimes we ship the kits with Alpha
potentiometers, they are clearly marked with "Alpha" on them and in that case no washer or
nut is needed under the panel.
