D-E771/E776CK 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 and 1/4 W or less unless otherwise specified. ў · : internal component. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. · U : B+ Line. · H : adjustment for repair. · Power voltage is dc 4.5 V and fed with regulated dc power supply from external power voltage jack. · Voltages and waveforms are dc with respect to ground under conditions in service mode. no mark : CD PLAY : Impossible to measure · Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. · Waveforms are taken with a oscilloscope. Voltage variat
