ICF-SW7600GR IC B/D 1 2 IC B/D IC B/D IC B/D 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 1/4 W or less unless otherwise specified. • ¢ : internal component. • C : panel designation. • A : B+ Line. • H : adjustment for repair. • Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. • Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances. • Voltage variations may be noted due to normal production tolerances. • Signal path.
