(In addition to this, the necessary note is printed in each block.)
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 Ωand 1/4W or less unless otherwise
specified.
•2: nonflammable resistor.
•5: fusible resistor.
•C: panel designation.
Note on Printed Wiring Boards:
•X: parts extracted from the component side.
•b: Pattern from the side which enables seeing.
• Indication of transistor.
•U: B+ Line.
•V: B– Line.
•H: adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark: POWER ON
• Voltages are takenwithaVOM(Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
