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 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 M). Voltage variations may be noted due to normal production tolerances.
