J. R. [. . . ] When control. (bias) voltage is not supplied to the base of
TR607 in abnormal condition , TR606 and TR607 ,
1. When an abnormal negative voltage appears at output TR601 turns off, TR602 turns on and TR603 turns off so that the relay, RL601 , keeps off in order to protect loudspeakers
from break- down.
2. While the relay, RL601 ,
on astable multivibrator repeat turning (switching) on and off alter-
nately each other by charging and discharging of capacitors
zero voltage(center voltage) controlling TR607 through D607 will increase, resultly the LED701 as protector indicator, starts flickering. When abnormal positive voltage appears at output ~, the voltage is supplied to TR602 directly, and the operation of the protector circuit is same as above mentioned 1,
keeps OFF,
resultly, the LED701 as protector indicator continues flikering. [. . . ]
