Piano, Brent Jessee's 6922's are $300. All these Telefunken tubes have the same exact numbers, including the new ones. His 12AU7's are also $300.
Nobody is cheating anybody, it all makes sense; NOS tubes cost more, even when the new and the old were made at the same factory. As best as I can figure it out, someone bought the old factory and began making the identical tubes.
From what I can recall in regard to discussions on these tubes, quality control was better then, even though the tubes look identical.
As I stated, the new tubes are fantastic; one was bad, and they had a good one on it's way before I got off the phone. That was months ago, and now I'm happy with no complaints.
Presently, the new tubes are sold out. Someone would have to buy both and compare to make a determination. Since I don't have the spare cash, it won't be me; I'm going to buy the new ones when they get them in stock.
