Hey David. Thanks for your note. It seems to me that you said about the same thing I did in my message--that after a certain point (1950s?) we lost track. Yet I suspect that all those variations are still on the same basic set of themes--and that's what I'm trying to get at. What themes are today's variations on?
And, sure, by the time you mix all that up, there may not be much left of the characteristic sound of that circuit--too much else going on. Or, rather, the sonic characteristics smear together and overlap to the point where it's not a useful guide to the sound. I acknowledge that.
But the basic topology is the backbone, it seems to me. I guess my question can be summed up as--can today's tube amp topologies be readily understood in terms of the classic designs? If so, then which basic designs are still important? If, on top of that, I know a bit about what those prototypical designs sound, or sounded, like, then I start to feel like I'm getting a handle on the subject--even if knowing the circuit would NOT allow me to predict much about the sound (and it probably wouldn't).
So that's the basic question: If I look at, say, the top tube amps in Stereophile's RC list, could I classify their topologies with reference to important designs of the past? Or are today's designs new in meaningful ways--beyond the choice of components and a riff here and there?
Cheers,
Jim
