specified.
• % : indicates tolerance.
• C : panel designation.
• U : B+ Line.
• H : adjustment for repair.
• Total current is measured with no cassette installed.
• Power voltage is dc 1.5 V and fed with regulated dc power
supply from battery terminal.
• Voltages is dc with respect to ground in playback mode.
no mark : PB (DOLBY : ON)

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