Tube amps are voltage driven which produce even harmonics,solid state is current driven which produces uneven harmonics.That pretty much sums it up,right.
Is this true? I'm no expert. Just been reading up on tubes lately, because I'm considering moving over to the dark side from SS. I've read that tubes produce both even and odd harmonics, and in push-pull tube amps the even harmonics (all of them?) cancel out leaving odd harmonics like a SS amp. I may be off on this, like I said I'm no expert. In any event, they produce some magical sound.
