SCHEMATIC DIAGRAM (AMPLIFIER)
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.
This is a basic schematic diagram.
