Can anyone give me a circuit for connecting a phone line to broadcast
over a stereo system?  I only want to use the stereo to amplify and play
over the stereo in a "one way" mode.  I know radio shack has a device
for recording into a tape player (costing over $20, which probably
consists of a 50 cent isolation transformer), but I would like to build
one cheaper.  I think that simply an isolation transformer would work,
but I don't know the ratio (or input impedance).  Any of you telephone
jocks out there that could give me a suggestion?
