c.)

  Solder 3 transistors, bending the components before soldering (otherwise they won’t be able to lay flush 

 

 

if soldered first). Make sure to match the shape of the transistors to the shape printed on the board.

 

d.)

  Solder 3 +47uF electrolytic capacitors (bending the components before soldering, otherwise, they won’t 

 

 

be able to lay flush if soldered first). Make sure to match the shape to the printed shape on the board. 

 

 

The long terminal is positive, the short terminal is negative.

i.)

  First estimate the capacitor pin from which position to do 90 ° bend

ii.)

  After folding the pin, insert it into the corresponding hole (pay attention to the installation direction, 

 

 

matching the shape of the board).

iii.)

 Bend the capacitor pin 90° in the correct direction and then solder it
