A feed resistor on the power supply panel used to go open circuit that feeds HT to the sound output valve , no sound obviously . If the PL509 line output valve glows on switch on check the boost capacitor on the timebase panel , they used to go short circuit regularly . Varying width is often caused by a loose slider on the width control ( timebase panel again ).
