It says made in the USA on my tube though?

 
You can be suspicious of printed labels.  I posted earlier about some 6ES8s (AKA, ECC189) I got.  They were labeled by Arcturus, but as was pointed out by the Lyr Tube Rolling Brain Trust, they are actually ECC88s from Holland, with two different size "halo getters."  And then one died.  Go figure.
 
So there's an old US company lying about what they were selling.  That's why factory codes are vital to identifying a tube, if they're visible.

ThurstonX is right. You can't trust those.

Surprisingly despite being counterfeit, they sound better than the stock GE tubes.  This makes me wonder what real amperex's sound like.

They don't even have to be counterfeit. This was a business where rebrands were common.

I would get gold lions from Upscaleaudio, if you are on a budget. If you have the money get yourself some Telefunken E88CC platinum tubes or some good Russian tubes. The stock tubes will sou n d a lot better after 200 hours of burn in. Moreover most tubes sound better after burn in, so make sure you burn in your tubes, to maximize there effect upon the overall sound signature.

I second the suggestion of putting more hours on the tubes, if you haven't already done that.

Hi there, I am thinking of purchasing the Lyr 2 to amp my Q701s because I am unhappy with the low end that my Audio GD NFB 15 produces on these cans.
 
Could anyone tell me if the JJ ECC88 tubes which come with the Lyr 2 will cut it with my Q701s, since  I am looking for more weight and depth in my music, specifically Classical music? Or should I seek different tubes to go with the Lyr 2 to achieve this?
 
I read that the Amperex Fat Bottle tubes (I think this means Russian-made) produce a really satisfying low end on the Q701s. Any advice or suggestions?

I am relatively new too the Group, Rob, Thurston, Oskari, are Pro's, but I have had great luck with Amperex Bugle Boys, Rob's Russian 6N23P's, the stock tubes are a bit bright, brittle, lacking in body and bass IMO. Welcome to tube rolling, my condolences to your wallet!

the 7308's arrived here yesterday absolutely worth the price in my book

Jay, how about a little review.  I have a 2 pair of USA made Amperex 7308 PQ's, 1965 O Getters like yours and 1960 D Getters.  Really like them on my WA2.  Nice wide soundstage, upfront presentation with a little more of a "raw" (in a good way !) sound than my Philips Miniwatt 188CC's.  Very "live" sounding.

haven't had them very long, but the very first thing i thought was how "live" or real the sound was. clear, 3d , fleshed out sound , texture.
if a tube could be "high end" i'd have to say this might be one ! now i can fully appreciate the term "holy grail"
more will be revealed as i get to spend more time with them.

It's time to play Name That Tube!
 
I love these CEis.  Always something different, since they were just buying and re-labeling.  I got a quad 6N23Ps a few weeks ago.  Pretty sure they were from this seller:

Interesting trio.  Any ideas?
