2-2. SCHEMATIC DIAGRAM

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
4
specified.
• % : indicates tolerance.
• H : adjustment for repair.
• Power voltage is dc 9 V and fed with regulated dc power
supply from external power voltage jack (J4).
• Voltages are dc with respect to ground under no-signal
conditions.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : AUDIO
J : RF
