HCD-GTZ4/GTZ4i/GTZ5

The IC800 on the POWER AMP board has been changed in the midway 
of production. The POWER AMP board and IC401 on the MAIN board 
have been changed due to it at the same time.
New/former discrimination, note of replacing the IC800 (Former type) on 
the POWER AMP board, printed wiring board, schematic diagram and 
electrical parts list of the POWER AMP board of New type are described 
in this service manual SUPPLEMENT-1.
Refer to page 59 on original service manual for the IC401 on the MAIN 
board.

Confi rm the serial number.

Former type

8827190 or smaller

New type

8827191 or larger

The IC800 (Former type) is limited to the stock quantity of service parts.
When the IC800 of Former type cannot be obtained, exchange the complete POWER AMP board.
However, the Former type/New type exist in the complete POWER AMP board due to changes of the IC800.
Do the work with reference to the following fl owchart.

HCD-GTZ4/GTZ4i/GTZ5

Note:
•  All capacitors are in μF unless otherwise noted. (p: pF) 50 

WV or less are not indicated except for electrolytics and 
tantalums.

•  All resistors are in Ω and 1/4 W or less unless otherwise 

specifi ed.

•  2 : Nonfl ammable resistor.
•  3 : Printed resistor.
•  C : Panel designation.

•  A : B+ Line.
•  B : B– Line.
•  Voltages are dc with respect to ground under no-signal 

(detuned) conditions.

  no mark : TUNER (FM/AM)
•  Voltages are taken with VOM (Input impedance 10 M

).

  Voltage variations may be noted due to normal production 

tolerances.

• Signal path.

Note:
•  X : Parts extracted from the component side.
•  Y : Parts extracted from the conductor side.
•
