I made this Video for William after a phone conversation about the NuTone 478 Apartment Intercom System where he lives - I had previously sent him link to some of our other Videos about the 478 System - and he actually used those Videos to figure out what was wrong - repair the problem and get it working - Good on Him! - Chris

Where could I get a new outdoor speaker?

Hi Ruth: We have all sorts of NuTone Speaker Cones, including the Entrance Directory for the NuTone 478 Apartemtn Intercom System. You can contact us directly about the Speaker Cone - Chris [e-mail]

having trouble finding the amplifier in an old building for a 4 apartment buzzer intercom setup. is it possible the amplifier is in the intercoms or is it possible there is no amplifier? it's an old lee dan system from the late 80s

Hi thehook: There should be an Amplifier (unless it was removed and that's why the system doesn't work) Amplifiers are typically located in utility areas or sometimes behind the Entrance Directory - Chris
