    Please help me!!!

    I have built the intercom circuit found at (
    http://www.uoguelph.ca/~antoon/circ/intercom.html ), but it does not
    work.

    Are the audio transformers necessary with the 8ohm speakers? I cannot get any noise on the line at all. No sounds comes out from anywhere.

    Any ideas?

    Thanks

    Do you have the test equipment to make some tests?

    Have you measured anything? If so post what you measured ... and where you measured it.

    There is nothing wrong with the design by Jan Hamer. You need to check and see what you have done improperly.
