Looking for a sequencer box for a model 552 doorbell chime. I know they are rare. Does somebody make a retro fit or do you have a good used one. If none of the above then how about schemetics and I will get one made. Thanks-Tom

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?
