3. Place and hold a piece of cardboard over the PCB, then flip the cardboard and
PCB in one smooth motion.
4. The transistors will fall down, but their height above the board is nicely set by the
heights of components already installed on the board.
5. Make sure that the transistor leads are straight up and down, then solder all the
transistor leads.

Watch the polarity. Make sure that the side of the capacitor with the negative sign is
away from the silk screen with the positive sign.

Install J1 and J2
Align each connector carefully with the holes in the board. Squeeze the connector onto
the board. Keep your fingers outside of the hole pattern so you don’t jab yourself when
the pins pop through the board. It will take a little squeezing and wiggling, but it fits very
nicely and securely. It will make a popping sound as it pushes into the board.
