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?

@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.

@mulveling  It’s a wonder young folks aren’t flocking to this hobby lol.

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. 

@decooney I run Harbeth 40.3 XDs with a Rogers High Fidelity EHF 200 MK2. Sounds really good, drives them with ease.

As many of us have learned through experience, buying new tubes from a trusted seller who actually tests and ranks their tubes matters too.

It does, (goes for new and NOS) and if you are running tubes like KT150’s new Tungsol’s are the only option. However Roger said the reject rate is pretty low on the 150’s, but not definitely not 0%.
