THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (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 Ω and 1/4 W or less unless otherwise specified.
•¢ : internal component.
•C : panel designation.

•U : B+ Line.
•V : B– Line.
•H : adjustment for repair.
•Voltages and waveforms are dc with respect to ground under
no mark: PLAY
•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.
