How longwe need open new amp making tube working stable

[kldguitar]

Commonly, when new tube guitar amp was finished, the tube worked in unstable statment, it need be lighted some time in order to its statment stable.
At present, we lighted tube more than 100 hours, It is too long .espicial , when many amps need light same time, it need long time and high cost largerly.
Otherwise in class AB amp, two tube need be matched, if they were found not matched after 100 hours lighted, we would have to look for new tube and start new light time.
I want to know we short this light time? How can we have way to short this time?http://www.kldguitar.com

What the fankus are you raving about and why start a thread with something like this?
For a "company" (and I use the term loosely)... building and selling vacuum tube amps, you make it sound like you guys couldn't pour piss out of boot if the directions were on the bottom. You are laughable and annoying at the same time, so stop while you can, otherwise what very very little credibility you might have will totally evaporate.

Confucius say "If tubes still changing characteristics after 100 hours, they probably junk"

if you do some googling you'll find that there's opinions and opinions about tube reliability, like that tube reliability on any particular tube generally goes way up if its been running okay for more than about 10 hours. (I have not yet discounted this hypothesis in my own experience). If a tube turns to sh*t early, it will still be sh*t in 100 hours and you're wasting your time. Given what I understand about thermodynamics (which is pretty minimal), I can't see how any bad tube will get better without serious intervention. I thought infact, that all matter in the universe tended naturally to entrophy into a more chaotic state without intervention, and i can't see how this would be any different with tubes (but could I be wrong about this? maybe?)

In my humble experience, modern tubes can have entire batches with reliability problems, which I guess depends on a whole range of manufacturing issues from bad materials to bad quality control to escalating cost of production forcing cost-cutting. A 20% dud rate used to be not uncommon in recent years, but more recently I've surprised myself how peed off I've been with purchasing several new dud tubes in a row...

As a guitar amp manufacturer (with hypothetically more buying and marketing power), you would theoretically have more clout in a marketplace situation (not to mention doing the tube world a big favour) if you sent all the crap tubes back to the dud factory they were made and told them where to stick their tubes, or at least tell them to get their act together to make better tubes. But I don't understand much about the way the market works in your part of the world

You also sound like you would benefit from finding a good translator to translate some decent tube tech books into a lingo you are more familiar with.

Um.... What Bruce said.
