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

Need new springs for the hammers. This is an old door bell and it has lasted about 40 years. The new ones are sick. This is the best I have heard and would like to keep it another 40 years.

I have the exact same problem, but it\'s not caused by a lighted doorbell. Without the doorbell connect (and not crossing the wires) the chime mechanism keeps repeating.
