I've seen several threads on using an amplifier to help generate a ring signal to old style rotary phones. I've looked at the circuit diagram here: Telephone ringing circuits
I have an amp, a Sony. I have a transformer, a Radio Shack model: 6v or 12v to 120v (mounted backwards). I have a soundfile on my computer, sine wave at 20hz. I have some resisters, (not the exact ones called for in the above diagram, but close).
But try as I might I can't make it work. Does anyone use this method? Can anyone help me figure out what I'm doing wrong?
