Resistor Installation

These resistors are all ¼ Watt, 1%, metal film resistors. Install these resistors into the

silk-screen side of the PCB, flush with the PCB. A 1 Watt power resistor will be installed

in a later section of this manual.

The diodes are rated at 1 Amp and 400 Volts. Diodes are polarized, so you must align the

white stripe on the diode with white stripe on the silk screen. Insert the diode into the silk

screen side of the board and solder them on the solder side. The diodes are installed flush

to the PCB. Note that LED's will be installed later.

Power Resistor Installation

Install R318, a 3.3 Ohm 1 Watt resistor.

LED Installation

Install LED1 and LED2. Unlike resistors, LEDs are polarized. There is only one right

way to install them. You can identify the positive and negative side of an LED as

follows:

1. Given uncut leads, the longer of the two leads is the ANODE (positive) lead.

2. Looking down onto the body, you'll see a round outline with a flat on one side.

That flat is closest to the CATHODE (negative) lead.

Lead spacing is 0.5"
