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.
• U : B+ Line.
• Power voltage is dc 3V and fed with regulated dc power
supply from external power voltage jack.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : SW
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• The voltage isn't filled in the measurement impossibility
place.
