Ebay: Buck Converter AC from your transformer goes on the input side, and you have adjustable DC output via the little flathead screw on the output side.

The speaker works fine on DC, I believe somewhere on the circuitry it was indicated it ran on 5v DC.

You'll need a voltmeter with a DC setting to set the voltage, but it works like a charm.

I have a second buck converter powering a couple of Lionel 9v battery sound systems that were boxcar take outs that I use to add sounds to the layout. One plays Halloween sounds and the other Christmas music, powered right from my transformer.
