  Nice tubes, the one on the right is a GTA style with side getter.
I think they are 57 and 56 production.

 
Thanks!
 
Interestingly, both tubes have 6SN7GT printed on the bottle. Did Fivre not label their GTA tubes "6SN7GTA"?

Here are a couple of my FIVRE both GTA type one marked GT the other GTA.
I don't rely on the markings but the internal structure.

The only structural difference visible to the eye appears to be the position of the getters? In your opinion, do the GTs and GTAs sound different? Unfortunately, as I just got them, I haven't had a chance to thoroughly audition and compare these tubes yet....

In my systems and my worn out and well used ears they do.
 
I find the GTA's (side getter) have a stronger bass.

This is very good to know. Thanks!

anyone familiar with Shuguang Treasure CV181-Z tube ??
 

 

[tagosaku]

I thought it was good. Not the same class with Syl W tall bottle, TS RP etc., but the best current production that I know of.

YMMV with how well the shuguang will sound like in your tube amp. apparently this guy was impressed and bought a whole bunch for his amp

opps think i have one in my warchest....fired it up,
sounds huge, spacious, easy on the ears. not brittle sounding, not too warmish mushy..good thumppp.  
( when it was new, there was this gritty sound, but it went off after about 100hours. now its silent. )
 
just flipped thru a few genres...  hmmm... very Un-annoying. v enjoyable i must say
 
( Just switched to a TungSol GTB...oooh myyy...every naunces dived down a notch...as if a veil settled over my setup... )
 
( Slot in a Sylvania WGT, a livelier tube vs the TungSol..
sounded it has more "steel" in its sound than the PsVane.. the drumhit are more taut..hi hats brighter.. quite expansive sounding too. )
 
=============
 
ohhh my...just put back the PSVANE...took out the Sylvania...no adjectives come to mind..cept to say that its so LIFE LIKE.
