Don\'t know what\'s wrong with the unit. Do ya\'ll know what the input voltage is supposed to be? The back of the unit says only use a \"no. 35 transformer\".

I have a Rittenhouse Emerson Elec Model C8326 (perhaps 1960's) that has stopped working today. The chimes and housing seem okay, but the mechanism and bell button are old and worn out. Do you have replacement parts - and at what cost?
