Wrong label on the board.
The 100uF electrolytic capacitors are replaced with 10uF.
Now, it’s time for more capacitors. Take the four 10uF and two 1uFcapacitors and place them on the front
side of the board. Be careful, these are
polarized!
capacitors and should be soldered the
right way
in.
There is a + marking on the circuit board that should match the long lead of the capacitor, the – side is
also marked on the body of the capacitor with a white strip. You might have to clip a little the jumper
header if they are in the way of the capacitors.
SUPER MEGA IMPORTANT!!! RESPECT CHIP
POLARITY.
Next insert the IC chips into their sockets of the bottom board. Again make sure that the
notch
on the
chips is
facing the same direction
as the notch on the sockets.
TOP BOARD
Now populate the top. Again start with the remaining 1k resistors and solder them in as well as the
transistors.
