Note:• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolyticsand tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specified.• U : B+ Line.• Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
• C : panel designation.• Voltage is dc with respect to ground under no-signal
(detuned) condition.no mark : FM
• Voltages are taken with a VOM (Input impedance 10 MΩ).Voltage variations may be noted due to normal productiontolerances.
