I've been accused (I think) of being a NOS snob. But look; in the 1950s when the 6DJ8 came into being, it was designed to be used as an RF amplifier for the -then- new UHF TV band. That market was HUGE! Billions and billions of tubes. Companies had the incentive and the means to spend a lot of money on research. Formulas for cathode coatings back then were as closely guarded secrets as the formula for Coca-Cola. Since the market was so huge, tubes being the only game in town, makers of the chemicals for those coatings had an incentive to provide a high purity product to the tube mfrs. We audiophiles may think we are an important market; but we are not. Even so, our market is dominated by the big players like AR who put a lot of price pressure on current mfrs. This can lead to QC issues like vacuum purity. It takes more TIME to achieve a high vacuum and time is money. The 6DJ8, 6922, 7308 family of tubes were designed to be 10,000 hour tubes. A decent pair should last several years. What I have a hard time understanding is why someone would pay thousands of dollars for a piece of equipment and then bitch if he has to pay more than a few bucks for tubes. Sure NOS tubes cost more. But they don't make then like they used to and aren't likely to in the future.
Is there a worthy 6922 presently made?
Why hasn't any tube manfacturer designed a good sounding 6922 tube? The paucity of decent designs only fuels the exorbitant price gouging the tube dealers are doing with NOS 6922/6DJ8.
I think it is pretty universally accepted among tube fans that the Sovtek 6922 is a dependable & strong tube, but a sterile, thin, & dead sounding device. Some have praised the JJ 6922, while others have proclaimed it rather mediocre, and some have blown up their amplifiers, like an ARC owner who burned out parts of his VT-100's circuit board when attempting to substitute the JJ's for the stock Sovteks in the input stage.
Sovtek's owner, New Sensor, has come out with a "new" 6922 in the form of an Electroharmonix 6922, with claims it is significantly better than the Sovtek. But some have said it is nearly the identical tube and sounds nearly identical. Audio Research claims it is a better tube, but.....
Why hasn't Svetlana designed a 6922? Or someone else? We are left with two tubes made by the same manufacturer, and one from Czechoslovakia. That's it! Any thoughts or experiences?
