50 WV or less are not indicated except for electrolytics

and tantalums.

• All resistors are in Ω and

W or less unless otherwise

specified.

• % : indicates tolerance.

• C : panel designation.

• A : B+ Line.

• Power voltage is dc 1.5V and fed with regulated dc power

supply from battery terminal.

• Voltage is dc with respect to ground under no-signal

condition.

no mark : PB

: Impossible to measure

• Voltages are taken with a VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal produc-

tion tolerances.

• Signal path.
