Like a lot of modern amps (the Vox AC30 CC2 included), it's driven by op-amps rather than valves, but it's still driving a good old fashioned spring tank.

Using op-amps ...


I have a Vaporizer (sounds good with decent speakers). It has an op-amp tank driver (no transformer) that gets pretty drippy. There is a current feedback in the circuit that compensates for drive-coil inductance - so it drives the tank like a triode and transformer would.

Not sure how the Vox circuit compensates. I have one and the reverb is fine for me, but it don't surf..... The Vox doesn't have the right bottom end for that anyway.
