Hi all, I want to replace my old battered plastic illuminated bell push with a stainless steel one. I've managed to find one here : http://www.alertelectrical.com/Door...-Bell-Pushes/Illuminated-Chrome-Bell-Push.asp but from what I can work out it runs at 8 volts. I've had the multimeter out on mine, and it seems to be 13.8v (it's an old Friedland transformer). Anybody know if this one will work, or do I need to look for a different bell push or transformer? Thanks.
