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.
• C : Panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
• A : B+ Line.
• B : B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER
• 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.
F : AUDIO
f : TUNER
N : MIC
E : VIDEO

Note:
The components identi-
fi ed by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
