From out of *nowhere* this snippet......

WTF is all this rubbish? Pinky still setting himself up as Valvefinder
General outside of ukra? :-)

None that haven't been previously discussed to death, certainly. After
all, were you expecting some *new* shortcomings to appear in a
technology that peaked half a century ago?

it is always more interesting to have some specifics to talk about,
Stewart . Let's take this one, for instance:

an OPA2604, with distortion cancelling cicruitry build in,
needs a *thousand* times more feedback to be even a
half decent match for a handfull of hybrid tube-SS parts.

comments ?

Actually, given the amount of feedback for which that opamp was
designed to be used, i.e. using it correctly, it is not a 'half-decent
match', it utterly *obliterates* anything you can concoct with tubes.

Show me the hybrid circuit which can combine a gain of 30, a bandwidth
of 500kHz, and distortion of less than 0.01% across the audio band.

What's wrong with feedback? Just because the phase stability of tubes
is so poor that you *can't* use much feedback, doesn't make it a bad
thing per se. It's called progress, Rudy.
