Greetings: I have hooked a couple of PA systems to the telephone line by purchasing Radio shcak Phone Amplifiers and modifying the microphone and speaker sections with audio transformers. The purpose of this is so that disabled people who are confined to bed or their house can listen to and partake in the conversation. Radio shack has discontinued the model I have used and before I go about reverse engineering another one, Is their a kit/schematics etc that I can get that does this. If not, can someone point me to where I can get information on hooking stuff up to the phone line? My knowledge of telephone electronics is presently zero, but I learn quick. Any help appreciated.
