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?

Uh, they can and they do. I've had no issues with many KT150's I've bought for my ARC amps, same with Electroharmonix and others- in fact, I've had no issues with any tubes I've bought.

We all like tubes and they do a better job than solid state.

 does anyone here have an understanding of what atube does within in an amplifier? Why are so many used in the more powerful amplifiers.

So the current flows through A vacuum tube versus a solid state circuit. ok, that's good info. What is being achieved with all these tubes? Current flows in and causes a filament to glow and then current flows out. So what's being accomplished?

In my case, I'm not talking about "issues" I'm talking about how I never tried NOS until very recently. I've never had and issues w/ Gold Lion, but the sound difference was remarkable when I used some RCA pre tubes and some Mullard input tubes. I am still running Gold Lion Power tubes and really dont see myself changing. Four KT77's cost me under $400 and will last me 2-3 years. I dont see myself spending 3 times that amount for the same time. Thats just me.

 

But, its not about issues, its about much better sound.

My question in the beginning was, why the difference in sound quality and I think we've had some fine explanations from the gallery.

Actually New “Tung Sol” efforts have been great …their el34b was my very favorite power tube.
