Actually we have a SVT-4PRO. Those of course have SS poweramps (MOSFET IIRC), unlike the SVT Classics. Much has been said about "the SVT tone" and whether it has something to do with tube poweramps or not.
Of course whoever affords SVTs probably also affords roadies to carry them and spare tubes.
I wonder if anyone has ever built their own SVT?
People have built their own Rectifiers and various tube poweramps but it's obviously not a trivial task.
Back on topic. Well, slightly

Anybody using class D amps?
