Wrong thread. Might be slight build difference, GT came out In the 40s not sure when the GTB came out, maybe after 56' and they're built to warm up quick, like 10 seconds. I can look up exact dates or someone can chime in with that,

Right, thanks.

I recently found this NOS Edicron 6as7g for a low price of $10. Although, I haven’t made direct comparisons and have only an hour of listening time.. it sounded nice!.. better than my RCA gray or black plates I think. I will compare it to my TS 5998 next.

It is dated 12-15-86, I know that Edicron rebranded tubes from various countries, USA=RCA, Russia, etc. Because this is labeled Made in UK, I’m assuming it’s a Mullard mfg. I just cannot for sure confirm this.. I’ve had a hard time finding others like it. Anyone know for sure?

The UFO getter would indicate it's almost certainly Russian. Mullard stopped making tubes altogether in 1982, and as far as I know never made a 6AS7 (6080 yes, but not a 6AS7).

Yep, the "flying saucer" getter holder tells us it is a Svetlana.

Is this tube NOS or New?

It is likely NOS. 6AS7G types were among the last vacuum tubes to be replaced by solid state devices. Similarly we often see WE 421As manufactured as late as the 1980's. And it's not uncommon to see these fairly late "Made in UK" Svetlana tubes. Buyer beware.

Edit: On the other hand, the Svetlana isn't a bad tube and $10 is a good price.

Tube appears nos from the 80s. I agree that the getter and year is probably a giveaway. Also nice to know that even the “made in country“ tubes were misleading the customer. Regardless, it does sound nice and different than my RCAs. I’m glad to have it in my collection. Thank you everyone.

 

[Ripper2860]

I'm holding firm on it being a Svetlana.

At least you now have something to hold that's firm.

I have an Amperex branded pair, except they were made in the England part of Russia rather than the UK part. Got them pretty cheap too, and they sound quite decent even though they aren't really Amperex.

It wouldn't be a problem if I could get the thought of you fondling your tubes out of my head.

Noooo! My Sylvania 7236 didn't light up last night... My youngest had a birthday party so I removed the tubes from the amps in the living room, but when I plugged it back in it stayed dark. I'm gonna try cleaning the pins first, and maybe try to re-solder them if that doesn't work.

Be sure to clean the socket too...
