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.
•
f
: Internal component.
• 2 : Nonfl ammable resistor.
• 5 : Fusible resistor.
• C : Panel designation.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : POWER ON
• 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.
• Signal path.

• MAIN board is multi-layer printed board. However, the
patterns of intermediate layers have not been included in
diagrams.
Note 1: When the complete MAIN board is replaced, refer

MAIN BOARD AND THE COMPLETE MAIN
BOARD” and “NOTES ON THE WIRELESS CON-
NECTION (LINK) AFTER REPAIRS ARE COM-
PLETE” on page 5.
Note 2: When the complete POWER board is replaced, refer
