Tony, I believe your thesis is incorrect in regards to my situation. It may be true in regards to others. I recently (3 years ago) replaced 18 year old Gold Lion KT-88s and ax-7s with the same. Flawless replacements. I'm positive they were not NOS. I could not be happier. I am not arguing that different tubes may produce a better sound. I am saying these Russian replacements arrived as advertised.
Why Can't Modern Tube Manufacturers Make a Proper Tube?
Current tube manufacturers, at least the ones I have tried should be utterly ashamed at their ineptness, apathy, ignorance, or whatever it is that makes them seemingly unable to make a tube properly.
And I never knew what I was missing before I tried reclaimed tubes from the 1950's, an era where people build things instead of ruining things.
The present manufactures are said to have the actual machinery to make tubes for which they have examples in hand and schematics on file, but they just can't do it.
Is this a case of Idiocracy? Are people just stupid today? The world and all creation do follow the 2nd rule of thermodynamics so I guess this is the case.
Listening to Black Plate RCA’s and Mullards in my system, even for a short time made it glaringly obvious that modern manufactures are embarrassingly inadequate. There is absolutely no comparison.
Why can't modern tube manufacturers make a proper tube?
1. lack of IQ?
2. Apathy?
3. Lack of Materials?
4. Lost knowledge?

I'm testing out the durability of the Linlai 6sn7 tubes compared to my kenrad's, the kenrad's don't sound quite as good as the Linlai, but I'm still on the durability stage, the Linlai have only been on a year on 24/7 , the kenrad's were on 24/7 for 3 years and still sounded good. Only time will tell now. |
@facten I know someone who has a quad of barely used NOS Shuguang Military 6L6GC (pre-1970, not blue box) available if you are interested.
AG is nothing compared to the Harbeth user group. Try posting anything about a tube amp there. They'll rip your head off and stake it. |
The proud new owner of my former modded Cary V12R tube amp, and his Conrad Johnson mono tube amps - runs his Harbeth 40.2s amazingly well. I also heard his 40.2s with his very best CJ Mosfet solid state amp too. Nice, but the more special tube amps performed at an entirely different level of sound and engagement in his particular setup. Some tube amps are more capable than others. Not every tube or amp works well with some speakers. When you find a great match, results can be truly rewarding.
