simulating in c plus plus. to discharge a 200uF/450v Electrolytic cap at the output takes longer time to discharge when we switch OFF the mains in No load / no lamp condition. .
Switching on the mains ( with PB1 ) while Cap is discharging gives high voltage spike and also giving hissing noise which may damage our speaker.
Ckt charges cap at 450v .
i need v.strng suggestion on this.
Or both!
