[Jukebox-list] What value is the volume control used on an AMI'i'?

[Wesley Dean]

    The reason of this 'blunder' is that this system uses a low impedance circuit with only two wires that is convenient in moving the control to a remote location. In the continued use of this system may be improved by using a 10 watt wire-wound rheostat. The only that occurs with this control is when it is adjusted. I have posted another message that describes a circuit with absolutely no noise.Wes
