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
specified.
• 2 : nonflammable resistor.
• C : panel designation.
Note:
The components identi-
fied by mark ! or dotted
line with mark ! are criti-
cal for safety.
Replace only with part
number specified.
• U
: B+ Line.
• Power voltage is dc 9 V and fed with regulated dc power
supply from external power voltage jack (J601).
• Power voltage is dc 12 V and fed with regulated dc power
supply from modular jack (MJ101).
• Voltages and waveforms are dc with respect to ground un-
der no-signal conditions.
no mark : Talk
• Voltages are taken with a VOM (Input impedance 10 MΩ).
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.
