With about 40 hours on a tubed microphone pre-amp I'm
now interested in increasing the timbre and micro-dynamics
resolution particularly in the 80 to 500 Hz range. My first
thoughts would be: Sovtek, RAM or Jan Philips NOS.
Any empirical suggestions?

Mullards would be better, of course, but they'll cost an arm and a
leg.

"Would be better"... in what regard?


Also, that's a common tube, so you might be able to find NOS
GEs and the like if you look around locally. Sometimes you
can find an old-timey TV repair shop that still has tubes floating
around.

Finding vendor sources for tubes isn't the problem. It's the
brand name I'm asking about in regards to the specific
application.
