6-3. SCHEMATIC DIAGRAM • See page 15 for IC Block Diagram.
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 Ω and 1/4 W or less unless otherwise specified.
•C: panel designation.
•U : B+ Line.
•H: adjustment for repair.
•Total current is measured with no cassette installed.
•Power voltage is dc 3 V and fed with regulated dc power supply from external power voltage jack.
•Voltages are dc with respect to ground under
no mark : PLAY

•Voltages are taken with a VOM (Input impedance 10 MΩ ). Voltage variations may be noted due to normal produc- tion tolerances.
•Signal path.
