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 am looking for a wiring diagram for a Rittenhouse, Spartan Electric, Fayettevile NC C8845 unit which is 30 to 35 years old. It seems to be either able to use two D cells or 16V transformer but I am got sure how to wire it up. Any ideas? Thanks.

Can you repair the solo kids on this 1950s era doorbell?It’s generally ok except that some of the parts that slide in the tubes to ring the chimes are lost. I could send it in or you could sell me the parts to fix it myself. Thanks,George Pond
