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,
