holes is given for each to help you pre-form them. When installed, each jumper
should lay flat against the PC board.

Save one additional resistor lead for connecting variable capacitor C16 later on.
Next, install the kit's transistors and diodes.
Positioning of these parts is
critical--they must be oriented correctly.

Locate the 2N3906 transistor (black plastic case), checking
identification markings closely. Find its flat side and align with the
printed outline on the pc board before inserting the leads. Install the
2N3906 at Q4 and solder.

Find the 2N3053 transistor (metal case). Install at Q3, inserting leads
all the way so the metal case rests against the pc board surface. The
metal "emitter" tab should point toward C29. Solder.
