SYMPTOM Dead.
CAUSE
Power supply failure.
ACTION
In the event of Q702 failing, other components in the power supply may also fail.
Check all components and replace any that are suspect.
When replacing Q702, also change C710 and R716.
Also carry out the following.
Check that a posistor has been fitted in series with R705 and a diode is fitted across
R716 ( anode to chassis ).
Check the value of R719 out of circuit. If it is a 1k resistor then fit an 2k2 resistor in
parellel with it. Later production sets had a 680R fitted.
Inspect all solder joints in the power supply and line output stage.
