You say gea electronics if it isn't too late insist on the scr pulsation and not gea If you want to know why get a pulsator from each and get Emrys to strip them on the kitchen table. Nothing wrong with the gea one just 4 times as many parts.
Been looking at the spec sheet & I think we are getting Milfos's own pulsators - something called "Auto Pulse S" ?
