SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINE
WITH MARK 0ON THE SCHEMATIC DIAGRAMS AND IN
THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.
REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE
PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR
IN SUPPLEMENTS PUBLISHED BY SONY.
PROTECTOR OPERATION CHECK
Thermal Protect
1. Short across TH801 with the power on.
2. Verify that the protector is operated and LD801 illuminates red.
3. Verify that the protector is released and LD801 illuminates green
when the short is removed.
4. Likewise, perform items 1 to 3 for TH802 and TH803.
Over Current Protect
1. Short between the positive and negative sides of the speaker
output terminal CN802 with the power on.
(Perform this shorting for each channel on FRONT and REAR.)
2. Verify that the protector is operated and LD801 illuminates red.
3. Verify that the protector is not released and LD801 remains red
even when the short is removed.
4. Verify that the protector is released and LD801 illuminates green
when the power is turned off and then on again.
Offset Protect
1. Short between the +12V terminal of CN801 and the BTL+ or
BTL– of the speaker output terminal CN802.
(Short between +12V terminal and BTL+ and between +12V
terminal and BTL–.)
2. Verify that the protector is operated and LD801 illuminates red.
3. Verify that the protector is not released and LD801 remains red
even when the short is removed.
4. Verify that the protector is released and LD801 illuminates green
when the power is turned off and then on again.
Chassis Short Protect
1. Short between the +12V terminal of CN801 and the chassis with
the power on.
2. Verify that the pilot lamp PL801 goes on.
3. Verify that PL801 goes off when the short is removed.

•IC Block Diagram
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
for schematic diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ωand 1/4W or less unless otherwise
specified.
•2: nonflammable resistor.
•A: B+ Line.
•B: B– Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REM terminals.
• Voltage is dc with respect to ground under no-signal
condition.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F: AUDIO
for printed wiring boards:
•X: parts extracted from the component side.
•: Pattern from the side which enables seeing.
Note: The components identified by mark 0or dotted line
with mark 0are critical for safety.
Replace only with part number specified.
