THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

For Schematic Diagrams. Note:

• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except f or electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

• % : indicates tolerance.

• f : internal component.

• 2 : nonflammable resistor.

• 5 : fusible resistor.

• C : panel designation.

• A : B+ Line.

• B : B+ Line.

•Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. No mark : FM

•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage v ariations ma y be noted due to normal production tolerances.

•Waveforms are taken with a oscilloscope.

• Circled numbers refer to waveforms.

• Signal path.

•Waveforms

For Printed Wiring Boards. Note:

• X : parts extracted from the component side.

• a: Through hole.

• f : internal component.

• : Pattern from the side which enables seeing.

• Indication of transistor.

Caution: Pattern face side: Parts on the pattern face side seen from (Side B) the pattern face are indicated. Parts face side: Parts on the parts face side seen from (Side A) the parts face are indicated.
