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:

Please refer to servicing notes (page 3) for system of TYPE A and B.

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.

f : internal component.

C : panel designation.

A : B+ Line.

U : B+ Line.

H : adjustment for repair.

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

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.
