Driver Tubes 6922

@tomcy6

Thanx for the info. Hopefully I wont get addicted to NOS, I just want two sets of AT7, AX7, 6922 and hopefully I’ll be set for life.

As to NEW, I am actually not that hung up on that. I’m annoyed that people list items as New Old Stock.....and they are not new.

How hard is it to say, "I sell used tubes I pull out of old radios. They test New and they’re awesome."

Thats how to do it. What if I sold a used scarred Mac 275 on Audiogon and I list it as NEW? That wouldn’t be right. But if I sell used tubes, I can call them new? Doesn’t make sense to me. Again, I don’t care if they’re used, but don’t piss in my ear and tell me it’s raining.

That’s all.

Hey @oddiofyl why did you buy that laptop just to look at the date & time up in the corner?

Tonydennison,

It is not unusual to have a tube fail soon after install, it's part of the deal using 50, 60, 70, 80 year old tubes......I suspect shipping has a lot to do with the failures. Most important is to have a vendor who stands behind his products, and Brent Jessee is one of the best tubes suppliers I am aware of. I've bought a bunch of tubes from him, and he warranted a couple that were DOA.

There are dozens of versions of the 12AU7/6DJ8 family and they are numbered differently in Japan/Europe/USA/Russia. I personally prefer Amperex 7308 or 6922 "SQ" or "PQ" gold pin tubes. I believe all of these were made at Amperex (owned by Philips) New York plant in Heerlen Holland.....going off of memory. Below is the best 12AU7 style tube information I've ever found and it is from Brent....talks about most all of the different tubes, and their sound characteristics as well

I am ZERO concerned about the failed tube....ZERO. Not upset not agitated not irked. I am not in the slightest bit upset or concerned about the failed tube.

I am sure Brent will do the right thing. I’ve never doubted it. I am not concerned about it.

I have had a few experiences of being demo's 6922/E88CC Tubes, as a result of being loaned valves for a using for Tube Rolling sessions.

All Loaned Tubes were tested, and perfectly matched as pairs.

All loaned Tubes were ranging from a production era from early 1960's - mid 70's.

There were Brands on offer from Mainland Europe, UK and USA.

In my Phonostage and DAC the Amperex Bugle Boy (I recall Orange Print) was a no go for myself and others who were present, the intensity of the high frequencies was too much for the ears to settle with.

As conjecture only, a overwhelmingly Bass orientated presentation might just come out with these as a viable choice to add a noticeable impact on the balancing  across the frequencies.

Other Tubes used as comparisons were much more of a 'what's your poison' experience.

My Phon's has selected for use, early 60's UK Tubes and the DAC has early 60's German Tubes as the selected type.
