2. DIAGRAMS

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
• X : Parts extracted from the component side.
• Y : Parts extracted from the conductor side.
• : Internal component.
f
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Indication of transistor.

For Schematic Diagrams.
Note:
• 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
1 / W or less unless otherwise

specifi ed.
• f : internal component.
• 2 : nonfl ammable resistor.
• C : panel designation.
The components identifi ed by mark 0 or dotted line with
mark 0 are critical for safety.
Replace only with part number specifi ed.
• A : B+ Line.
• B : B– Line.
• 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 production
tolerances.
