The nuvistor is a miniature valve, as also is the made up name Trivistor being a 5703WB in fact.
So in reality you only have the choice between valve (tube or thermionic) or solid state amplification.
The choice is huge but expect to pay more for quality valve amplification, one of the critical components is the output transformer and good ones aren't cheap.
I love Hendrix for so many reasons. He was so much more than just a blues guitarist - he played damn well any kind of guitar he wanted. In fact I'm not sure if he even played the guitar - he played music. - Stevie Ray Vaughan
