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. � ¢ : 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. V : B� Line. H : adjustment for repair. Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM ( ) : TAPE PLAY < > : TAPE REC (( )) : CD � : 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 variations may be noted due to normal production tolerances. Circled numbers refer to waveforms. Signal path. F : FM f : AM E : PB a : REC J : CD
