Next solder in the four BS170 unipolar transistors, two 2N3904 NPN transistors and two 2N3906 PNP

transistors. Take care that they are oriented the same way as printed on the board.

BOTTOM BOARD BACK SIDE

Take the 10 pin power connector and place it also on the back side of the board. It might be tricky to

solder it straight, but you can place something like your cutter under the board to hold it level. Also first

solder in just one of the pins, then take the board in your hand and re heat that pin while pressing down

on the header to align it ( be careful though, you don’t want to touch the pin you are heating up) wait for it

to cool and solder the rest of the pins. Do the same for eight jumper headers.

ATTENTION!
