I know this chime assembly is very old but is there a replacement kit for the hammers. they are sticking and perhaps the springs are just too soft. I\'d appreciate any help you can give me.

The Rittenhouse door intercom answering system system was installed in 1978. It is not functioning well. Do you have a newer replacement for it that would still have the doorbell and intercom system? Does a new unit come with the exterior speaker?
