Note on Schematic Diagram:
• All capacitors are in μF unless otherwise noted. (p: pF)
50 V or less are not indicated except for electrolytics
and tantalums.
• All resistors are in  and
1
/4 W or less unless otherwise
specifi ed.
•
2
: nonfl ammable resistor.
• C : panel designation.
• A
: B+ Line.
• B : B– Line.
• H : Adjustment for repair.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
L : USB
