Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. p: pF.
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and

W or less unless otherwise
specified.
•
f
: internal component.
• 2 : nonflammable resistor.
• C : panel designation.
• A : B+ Line.
• H : adjustment for repair.
•Total current is measured with no cassette installed.
•Power voltage is dc 9 V and fed with regulated dc power
supply from battery terminal.
•Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
