INTEGRATED STEREO AMPLIFIER

CAUTION

1. Parts identified by the A symbol on the schematic diagram and the parts list
are critical for safety.
Use only replacement parts that have critical characteristics recommended by

the manufacturer.
2. Make leakage-current or resistance measurements to determine that exposed
parts are acceptably insulated from the supply circuit before returning the appli-

ance to the customer.
