Powering an XPS-AB with different adapter?

[Zoobiedood]

I have a Variax Acoustic, and I'd love a lighter, smaller power supply to power the XPS-AB. Does anyone know if something like a One Spot (with L6 adapter) would work? The L6 power supply is comically large and heavy.

9VAC @2100mA is required

I have about 3 of those already...I was hoping something lighter and smaller could be used.
