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.
• C : panel designation.
Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.
• : B+ Line.
• : B– Line.
• Voltages are dc with respect to ground under no-signal con-
ditions.
no mark : Power on
∗
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10MΩ).
Voltage variations may be noted due to normal preduction
tolerances.
• Signal path.
