again, I don't think you know all you think you know about tubes. If you don't know how to design an amp, and you don't know how important power tubes are... then you don't have any credibility with me... PERIOD.
for the record my uniteds were bought at a 'going out of biz sale'... they are american made NOS tubes I paid $15ea for and have read that they are considered 'pretty decent'.
"The people I mentioned could absolutely design an optimum preamp setup tailored to anyone's wishes and needs."
1) if you think you/they have "special advice" that can yield an especially good set of tubes for an amp w/o ever auditioning them... well it just points out how little you know about tubes AGAIN.
Each one is different. Even two NOS tubes made in the same factory in the same year will sound entirely different.
So this advice of yours = crap.
They guy I currently buy tubes from lets me bring my amps in and audition several sets and decide what I think is best...
oh, and he actually knows how to build a tube amp... not just pop off at the mouth about his secondhand tube knowledge.
2) If we are talking about a pre cbs bassman... sure, I would def want to go find a rare set that was as similar as possible to the the original spec... this is because the original amp was designed to run on those tubes.
if we are talking about a mesa subway rocket... then nos tubes might not be the best solution. a modern amp was not designed to use nos tubes. and to say that
that amp WILL sound better with a set of NOS tubes that you haven't even auditioned is about as silly as saying power tubes don't matter.
here's what gibson says on the subject...

on how output tubes do matter:
"In addition to having their own sonic characteristics according to type, different makes of the same types of output tubes will also sound slightly different."
they also have a little section about tubes and suggest that NOS is not ALWAYS the best...
they also talk about true bypass and how it may or may not be the best solution if you have ONLY A FEW PEDALS!!!!!!!!!!!
yet another source suggesting that your "magic beans" aren't all that magic after all...

"Beware….just because a tube was made long ago & has never been used does not make it a 'great tube'. I once had a customer come check out one of my amps {loaded with JJ ECC83S-12AX7A tubes}. It sounded nice and he loved the amp & was ready to buy, then told me of his commitment to NOS tubes. He loaded up my amp with expensive mullard tubes that he had brought with him, and the amp sounded awful! Noisy, static, you name it. He looked at me and said 'what's wrong with your amp?
...
NOS tubes are not the best application with
every amp."
here's another guy that does amp repair and seems to disagree with "your highness" about NOS tubes... and look - he has a list of recognizable clients he does work for.... wha?
who do you do work for again?
"I studied electronics in my last year of High School and in my local Community College and graduated with honors in 1979."
where is your degree from???????????

"Many Russian and eastern European tubes are as good or better than some NOS alternatives and are much more attractively priced. We use carefully chosen selections from this category for most work. The choices are based on tube reliability experience and
listening tests as well as the amp application.
Recently, several new tubes have appeared on the market that are much improved over what was available in years passed. I am constantly on the lookout for the latest news and I try as many new tubes as possible. When I find a good tube for a reasonable price, I use it."
to stare evidence like this in the face and still be unwilling to admit that it is AT LEAST POSSIBLE that NOS is not always best is like burying your head in the sand. But then you did the same thing with true bypass vs buffered bypass so why should I be surprised?
I CAN ADMIT THAT SOMETIMES NOS IS BETTER. I CAN ADMIT THAT SOMETIMES BUFFERED BYPASS IS OK... SO WHO'S THE ELITIST HERE?
