Made improvements to PA cooling. Fitted soft start to power supply but it produces too high volts without a variac on the mains input so looking into fitting a regulation circuit to keep it down to say 35 or 37 volts which also remove any problems caused by the variac fluctuating or spiking (may have been cause of PA failures). Further bulletins will follow. Regards, Gary - G4WGT - IO83qp Web : http://myweb.tiscali.co.uk/wgtaylor
