NOTES
1. The heavy lines on the schematic denote the primary 4. On PC board drawings, Square pad indicates:
signal path. a. Polarized Capacitors - Positive
b. Diodes - Cathode
2. Unless otherwise noted, all voltages indicated on the c. Others - Pin 1
schematics are measured under the following conditions:
a. AC input at 120 volts, 50/60Hz. 5. WARNING
b. All voltages are +/-10% with respect to ground. A Parts marked with the symbol have critical
high impedance (10 megaohm) voltmeter must be used. characteristics. Use only replacement parts recom-
mended by the manufacturer.
3. Unless otherwise specified:
a. Resistor values are in ohms.
b. Capacitor values are microfarads (uF).
c. Inductor values are in microhenries (uH).
