SCHEMATIC DIAGRAM Ñ MAIN SECTION Ñ CFS-B5LMK2 Note: ¥ All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. ¥C: panel designation. Note:The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified.¥U: B+ Line. ¥ Total current is measured with no cassette installed. ¥ Power voltage is dc 9 V and fed with regulated dc power supply from battery terminal. ¥ Voltage and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM < > : PB << >> : REC¥ Voltages are taken with a VOM (Input impedance 10 MW).
