specified.

•

: B+ Line.

•

H

: adjustment for repair.

• Power voltage is dc 9V and fed with regulated dc power

supply from external power voltage jack (J101).

• Voltages and waveforms are dc with respect to ground in

service mode.

• Voltages are taken with a VOM (Input impedance 10 M

Ω

).

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.
