6-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS

Note on Printed Wiring Board:

•X: parts extracted from the component side.

•Y: parts extracted from the conductor side.

• : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

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

Note on Schematic Diagram:

•All capacitors are in ∝ F unless otherwise noted. pF: ∝∝ 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.

•C: panel designation.

•A: B+ Line.

•Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords.

•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 produc- tion tolerances.

•Waveforms are taken with a oscilloscope.
