ASSEMBLE COMPONENTS TO THE PC BOARD
After each step, put a check in the box located next to the step that you have completed.
Place the PC board on a table with the copper side facing up and insert the four input sockets into the PC
board holes as shown in Figure A. Solder the input sockets to the PC board as shown in Figure A. Apply
enough heat to allow the solder to flow around the input socket.
Insert the six transistor sockets into the PC board as shown in Figure 1 and then solder into place.
