Note on Schematic Diagram:
• 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
c o
specified.
• 2 : nonflammable resistor.
.
• 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.
m • Power voltage is dc 9 V and fed with regulated dc power
supply from battery terminal.
1 / W or less unless otherwise • Voltages are dc with respect to ground under no-signal
4
conditions.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
