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 1/4 W or less unless otherwise
specified.
Note : The components identified by mark
!
or dotted line
with mark
!
are critical for safety.
Replace only with part number specified.
•
: nonflammable resistor.
•
: B+ Line.
•
: B- Line.
• Voltage is dc with respect to ground under no-signal conditions.
• no mark : POWER ON
• Voltage are taken with a VOM (Input Impedance 10 M
Ω
).
Voltage variations may be noted due to normal production
tolerance.
• Signal path.
