THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
•
X
: Parts extracted from the component side.
•
Y
: Parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)

Parts on the pattern face side seen
from the pattern face are indicated.
Parts on the parts face side seen from
the parts face are indicated.
• AMP board is multi-layer printed board. However, the pat-
terns of intermediate layers have not been included in
diagrams.
• Indication of transistor.

50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in

ed.
•
C
: Panel designation.
•
A
: B+ Line.
• Power voltages is dc 14.4V and fed with regulated dc
power supply from ACC and BATT cords.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

• Voltages are taken with VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.

Note 1:
When the complete MAIN board is replaced, be sure to refer to
“NOTE OF REPLACING THE MAIN BOARD” on page 5.
Note 2:
Among the parts listed in the electrical parts list (page 55 to 65),
parts described as “Not supplied” can not be replaced for repair-
ing individually.
If a part that can not be replaced for repair is defective, replace
the complete mounted board or the whole parts including the
applicable board with a new part.
Note 3:
Individual electrical parts that mounted on the KEY board can-
not be replaced.
When the KEY board is defective, replace the front panel assy
(Exploded Views: Ref. No. FP1) including the KEY board with
new parts.
Also, block diagram, schematic diagram and printed wiring
board of the KEY board have not described in this service man-
ual.
