Rittenhouse Service & Repair Forum

I have a Rittenhouse Home Intercom, Model No. M7010 that had no audio. A technician said the amplifier was bad and he replaced several transistors in it, but the volume is very weak. He does not know exactly what transistors to use to replace the old ones, and does not have a schematic. Can you provide a schematic, or tell me where I might get one? Thanks, Tom Mitchell

I have a Rittenhouse door bell model c8355 and the transformer (that is what I think it is) has failed & does nothing but hum. Can I get a new transformer? or can I buy a replacement at the local home depot or Lowes?

Is there a new updated unit (with new bells & whistles) that can use the existing wiring and wall recesses of the old units. If so, where can I get them and what would be a ballpark pricing? Thanks
