Let's continue with the Handclap section. First add resistors. Do not pay attention of resistors type on the picture you certainly have different resistors.

Add film capacitors. On v1.02 mainboard C168 has been removed

Add electrolytic capacitors. Electrolytic capacitors are polarized, the long leg of the capacitors is the positive. Pay attention to orientation in which you solder electrolytic capacitors. The black part on the silkscreened electrolytic capacitor symbol is negative.

Add diodes. Diodes are polarized, the black ring must match the symbol silkscreened on the PCB.

Now, add transistors. Pay attention! There are three different type of transistor: 2SA1115, 2SC2603 and 2SA798. Do not mix !

Now, check handclap section power voltages and add ICs. Do not overheat ICs pins during solder process! Pay attention to BA6110 orientation. (look at the picture)

Add TM1 10kohm trimmer. TM1 adjustement is decribed on PCBs top silkscreen. A complete explanation is available in "finished" section.

Finally, add the potentiometer. Pay attention to potentiometers value they are all different. Then handclap section is finished, let's go to the Hihat section.
