SCHEMATIC DIAGRAM (AMPLIFIER)

This is a basic schematic diagram.

PRODUCT SAFETY NOTICE

Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol

!!!

and

mark in the parts list and the schematic diagram designated components in which safety and

performance can be of special significance. When replacing a component identified by

!!!

and

, use only

the replacement parts designated, or parts with the same ratings of resistance, wattage or voltage that are
designated in the parts list in this manual. Leakage-current or resistance measurements must be made to
determine that exposed parts are acceptably insulated from the supply circuit before returning the product to
the customer.
