TR909 clone Nava

Let's continue with the rimshot 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 C167 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 two different type of transistor: 2SA1115 and 2SC2603. Do not mix !

Now, check rimshot section power voltages and add ICs. Do not overheat ICs pins during solder process!

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