Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. � A : B+ Line. � B : B� Line. � Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark : TUNER � 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 : TUNER E : TAPE1/DAT IN a : RECOUT d : TAPE2/MD IN J : CD I : PHONO
