1-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Boards:
•X: parts extracted from the component side.
•
: Pattern from the side which enables seeing.
Note on Schematic Diagram:
•All capacitors are in µ F unless otherwise noted. pF: µµ F 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.
•2: nonflammable resistor.
•5: fusible resistor.
•C: panel designation.
Note: The components identified by mark 0or dotted line with mark 0are critical for safety.
Replace only with part number specified.
•A: B+ Line.
•B: B– Line.
•Voltages are dc with respect to ground under no-signal conditions.
•Voltages are taken with a VOM (Input impedance 10 MΩ ).
Voltage variations may be noted due to normal production tolerances.
