For 6AS7G tube rollers here ..... - Page 97

post #1441 of 1528
Yeah but we KNOW they were not made in 2011, or any time past the mid 1980's.

I know we debated a while back as to whether TFKN ever made a 6080 but I'm sorry I don't recall the conclusion.

I don't know who made the tube, but the code 20121 (not 2011) suggests that it wasn't Telefunken. The code was longer on tubes made by Telefunken, and started with U (Ulm) or B (Berlin). Tubes sourced from other manufacturers carried this shorter code. It's a date code, by the way, in this case 02 Nov ?2, perhaps 72.

Even so that code just looks strange for a Telefunken tube. Found something closer with an answer with another Ebay post.

P.S. My guess it is a GE  tube due to the boxy top with a "Lid" partly open

 

I got a bunch of those GE tubes at a much lower price. Not a bad sounding tube for the money.

The dot pattern screams GE.

 

The code is perfectly fine for a Telefunken-branded tube not made by Telefunken.

It is absolutely a GE tube. If you look at the other pictures on my other Ebay post you can see the GE dots.

Thanks guys! I was pretty sure they were American-made and John's link confirms it. :)

Although this thread seems to have gone a bit cold, I would just like to say a big THANK YOU to all who have commented on the GEC 6AS7G - you helped cement my move to these as 'power' tubes in my LD MKIV SE.

 

Although I found the Chathams paired extremely well with my C3GS drivers, comments re the 5998 had me hungering for more...but as their electrical difference seemed too risky for my unit, I looked more closely at the GECs. despite their rarity and cost! Luckily, I managed to find a pair of CV 2523s (NOS) for not much more than final cost of 5998s shipped to the UK. And all I can say is..WOW!  Everything described about these 6AS7G types certainly is true - no undeserved hype here. So I don't need to tell you guys just what I am now getting...I am now in sound nirvana - that's all I need to say!

 

Cheers...my final modded LD...

Imagine those guys with CRACK(You can buy 2 crack for the price of that LD without those tubes)They're using similar tubes and more expensive/exotic tubes.

post #1453 of 1528
At a local headphone meet, I let a Crack owner try my GEC 6AS7 on his amp. After warming up for 15 mins and listening for another 2 mins, he promptly turned it off and returned my tube. He told me it was so good that if he listened any more, he would have to empty his wallet and get one himself.

I'm still hunting for a rounded-base pair, but I do not look forward to finding out how much they cost now...

Sylvania 7236.  Very nice if you like your sound crisp, clear and delicate.  Not for baseheads though.  All 'IMO'.
