- 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.
-
- Regards,
-
