Let's continue with the hihat section. First add resistors. Do not pay attention of resistors type on the picture you certainly have different resistors. RA9B 10kohmmust be a resistor you measure at the beginning of assembly.

Add film capacitors. C151 and C160 have to be polystyrene capacitors.

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:2SA798, 2SA1115 and 2SC2603. Do not mix !

Now, check hihat section power voltages and add ICs and 28 pins IC socket. Do not overheat ICs pins during solder process!

Finally, add potentiometers. Pay attention to potentiometers value they are all different. Then hihat section is finished, let's go to the Ride/Crash section.
