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 diagrams.
Note:
• 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 Ω and
1 / W or less unless otherwise speci-

fied.
• : internal component.
¢
• C : panel designation
Note:
The components identified by mark ! or dotted line with
mark ! are critical for safety.
Replace only with part number specified.
• U : B+ Line.
• V : B– Line.
• Voltages and waveforms are dc with respect to ground under
no-signal (detuned) conditions.
no mark : PLAY
• : Impossible to measure.
*
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tol-
erances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tol-
erances.
• Circled numbers refer to waveforms.
• Signal path.
