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-signal
conditions.

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