Single Ended Triodes (SETs), the ultimate tube lovers dream.

Re: help me sort out the sounds (45, 2A3, 300B)

"Please -- anyone -- correct me if I'm wrong; but, the common wisdom seems to be: use the 45 if you can; if you can't, step up to the 300B."

I guess that's true at the moment. Only a few years ago, it went more along the lines of "the 45 is overpriced, unavailable, and under powered, and the 300B is lush to the point of being bloated. Only the 2A3 is really neutral."

A few years earlier, the 300B was the only "real" SET, everything else lacked the last bit of refinement.

These sands are almost guaranteed to shift again. :^)

Other than power capability, the only technical differences among tubes that I know to be audible are linearity and mechanical resonances. Both are entirely related to the mechanical design, and in today's SET world you can get many different mechanical designs in each tube type. So I am especially suspicious of broad generalizations about tube types. (Of course, I am also a circuit designer, so I feel that circuit design and parts selection are at least as important.)
