LOL...your addiction is now cureless
Never heard a J-tube in the 6AS7G family, but it looks like an RCA 6AS7G to me.
Not sure if it's a rebranded RCA, or manufactured according to RCA's design.
If it sounds like an RCA, I will stay away
Where do you find all these magnificent toys!? I did a quick look up (Google my go to search engine) and found a listing with this infoEver try one of these? Not sure who all might have made this particular type. Other than the Matsu 7DJ8 (not an uber-tube but pretty good for the money) I've not heard a Japanese-made tube that got me excited. But you never know where a diamond in the rough may lurk...

"Nippon Electric was a post WWII subsidary of Western Electric in Tokyo, Japan. The 6520 was a premium, high-reliability version of the 6AS7G. The only other company to manufacture this model of tube was Tung-Sol Chatham".
Very interesting story on your purchase...
eBay is a mine field...sometimes people can find real good deals, but sometimes liars and duds.
Rebranding is very common in tubes, 6080 is no exception. You are right TungSol and the RCA on the right are identical, they are both RCA 6080's I believe. I also think the RCA with orange print is actually Sylvania 6080.
So I think from left to right you have: NEC 6AS7G ----------- RCA 6080 (rebranded as TungSol) -----------Sylvania 6080 (rebranded as RCA) -------------RCA 6080
My windows 10 update knocked out the Topping D10 drivers.. (sob) and it seems like the Topping website is down for now... So getting use to the back up unit.. sort changes the sound signature of everything in a suttle way, gonna be a tube rolling weekend ahead
So will I.Bummer on the update thing, but nice that you have a backup!
Received the Tung Sol 7236 tube today. Tests great...very much appears to be NOS. But construction is very different from the Cetron. About the only thing in common is the medium gray box plates, but even with those the Tung Sols plates are longer with different extensions. The TS has a taller bottle, dual rectangular getter holders up top (Cetron has dual rings), different micas, etc etc. Possible the year of manufacture has something to do with it but I doubt it. Guessing the Cetrons were NOT made by Tung Sol. I'll be quite interested to see how they compare once I can listen to them.
How's the burn in going with the Cetron? How does it compare to the Tung Sol?Bummer on the update thing, but nice that you have a backup!

You got the Darkvoice amp? -----------> https://drop.com/buy/dark-voice-366seDon't know yet. Still waiting on the amp to listen to them in. Some of the non-electronic parts for this amp (like the transformer cover) are sourced from China, and for some weird reason there's been a delay on those. Can't wait to hear these tubes, but as this will be my first OTL I don't have any other amps on hand to try them in.
