    I'm looking for a simple AUDIO TRACER circuit or other means to hear were the audio is missing on this CONN organ. All I have is a multimeter and an old Knight VTVM. Any help will be appreciated.

    Do you have an audio system with provision for external input?
    Failing this, use a portable radio with the input across the volume control.

    It depends on whether the organ is transistorised or valved.
    A 100k resistor in series with a 100nF capacitor should protect the radio in most cases and pass sufficient signal.
