Assembly Instructions - Elenco Electronics AM/FM-108TK Assembly And Instruction Manual

ASSEMBLY INSTRUCTIONS

We will begin by installing resistor R43. Identify the resistor by its color and install as shown in Figure A. Be careful
to properly mount and solder all components. Diodes, transistors and electrolytic capacitors are polarized, be sure
to follow the instructions carefully so that they are not mounted backwards. Check the box when you have completed
each installation.
