Schubert, The US is far more inclusive than Germany. We are not divided into the super rich and the poor. America is still the land of opportunity, currently less opportunity than usual because of the policies of our current government, but we will get through this and come back strong. We fear no one and take great pride in all the good we have done and continue to do at home and around the world. Germany does not come close to our accomplishments in this area.
Angela Merkel said that Germany is not a nation of immigrants and doesn't want to be one. That doesn't sound too inclusive to me.
Sorry for going off topic but I can't stand anti-American BS. |
Deutschland uber alles, so to speak, no? I guess Sylvania, RCA and Tung Sol are chopped liver. |
The German work force was/is the best educated and trained in the world. When they get something right, they get it really right and vice-versa.
Germans have pride because everyone is included in, unlike the US where everyone but the super-rich is included out and you have to fight your way in.
Consequently , in the USA the dominant sentiment is fear, not pride. |
I don't think you'll find anyone emulating the materials or manufacturing practices of Telefunken today. Totally different eras.
Today's manufacturers use computers, modern materials and manufacturing techniques to optimize the sound of their tubes while Telefunken used materials and manufacturing techniques that are no longer feasible. |
@Mr J- The author of that article would have made Julian
Hirsch very proud. I'm certain, if he had reviewed tube
equipment; he wouldn't have heard much difference either. The
sonic differences between various iterations and year of
manufacture, within the same
family of tube, and the various brands, are usually anything
BUT subtle or, "tiny." Nor, in my experience, are
the differences dependent on the equipment(usually). |

Actually; some of the best tubes were manufactured for, "Post Germany" in the 1950's -60's. ie: The CCa is a special low noise, low microphonic, long-life E88CC/6922. Philips had similar designations for the Dutch Post, some tubes that were selected had PTT and BP lettering or etched designations, but they were the same as a top specification E88CC. The, "German and Dutch Post" consisted of telephone, telegraph, and telex, tube technologies, which required a very low noise E88CC/6922. A CCa is the same as a 6922 but was tested and certified with high mA, RP, and Mu and lowest-noise audio threshold. Most of the telephone centrals used vacuum tube technology equipment for telephone equipment, requiring a "noise-free" environment. The ECC803S(1950's) was selected for long life(10K hrs), S/N ratio and ultra-low microphonics, for use in avionics/aircraft radios. The letters, "CC" probably equate to, "double triode." For a special low-noise design, in the 6922 family; the frame-grid inner construction, was actually invented by Amperex USA, and appeared everywhere in the 6922/E88CC designs of the day, including Siemens Halske, Telefunken, Amperex, Philips, and many other brands. |
looking for technical details.. was there a particular design, materials or construction principle? What would say of a newer tube "they are emulating how telefunken tubes are constructed"? I can see tube manufacturing differences but which mattered? |
Regardless of how or how well they're made, what do Telefunkens sound better than? Amperexes? Mullards? Siemenses? Brimars? Valvos? No definitive answer. |
It was the war, WWII to be exact. That's when all the really good sounding tubes were made. Radar and communications systems. |
I suspect it has to do with the companies size, long history, and demands of the various applications its tubes have been used for over the years. |
|
My favorite tube for "least distortion and fastest transient response" is a pair of Sylvania 12AU7WA mil spec. This particular pair came in unopened boxes used by the US military back in the 60s.
I've tested quite a few, but must say, never Telefunken. |
I might mention, as I have elsewhere; the EAT tubes are the
closest anyone has come, in recent years, to the quality of
the earlier products. But then the OP mentioned cost!

Dunno! I've a box of other brands and they are all shadows of the Teles. Just replaced a set of JJ ECC803S (yeah,right) with old Dynaco branded Teles that I've had running for years in another preamp. Bang, bye bye JJ. Don't cryo. Amprex Bugle Boys are good too. |
replace German engineering? Keep dreaming... |
The Germans have been absolutely anal, with regards to
materials, quality and engineering excellence, for a great
many decades. The notion that someone else's products(new or
old) could exceed their standards is laughable. I've tried a
number of other tubes, and would not consider any nine pin
miniatures, other than either(50's or early 60's) Siemens or
Teles. Right now; my CDP has six Siemens(grey shield) CCa's
in it. The proof is in the listening! Then again; there are
many out there that appreciate the colorations(ie:
warmth/tubiness) of other brands. To each their own. |
