>I would not do it.  Audio transformers won't work either.
>You could try a DC-powered monaural audio amplifier, maybe a kit.
>Terminate each speaker in a load resistor, maybe 10 ohms and 5 watts.
>Experiment with 1 k to 50 K resistors in series with the audio amp input
>and the high side of each speaker termination resistor.  It's a basic
