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. � % : indicates tolerance. � Components for right channel have same values as for left channel. Reference numbers are coded from 200. � C : panel designation. � A : B+ Line. � H : adjustment for repair. � AC voltage readings in the bias oscillator with a level meter. � Total current is measured with no cassette installed. � Power voltage is dc 6 V and fed with regulated dc power supply from external power voltage jack. � Voltages are dc with respect to ground under no-signal conditions. no mark : playback ( ) : record < > : fast forward [ ] : rewind �� �� : pause I : NORM II : CrO2 IV : METAL � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Signal path. f : playback
