Can the DV use QA2408 tubes to replace 6sn7 tubes?

Hey tube masters,
 
Just got my 336 from a quitting friend Now the question is, what are these tubes?
 

 
Both are the 6sn7 but upon reading I saw so much tube names, even in the same brand... and I got confused 

 
Also can someone post a picture of the RCA 6080? Do they have any variants? Mine have a silver base, and reads RCA Radiotron Electron Tube. There are also smaller print saying 'Made in u.s.a. 56-30'. Has a chrome top - silvery/mirror top that is not so even..? On the glass it says 6080 and nothing else.

Unfortunately this thread doesn't get much love nowadays. You might want to try the 6SN7 Tube Addicts thread regarding those 6SN7GTs.

I'm not a specialist in different versions of these US tubes but I think that they are what they claim to be, i.e. RCA and Sylvania tubes. Apparently flat-plate Sylvania 6SN7GTs exist although there are other more common types.

Are yours like the RCAs here http://www.geocities.jp/radiomann/HomePageVT/Audio_US_Triode.html#6080?
 
In general, good photos of the tubes including all the markings on them are essential when trying to identify them.

Hello.
Someone met tube Sylvania 6SN7GT "Bad Boy" with yellow marking for base? Is very interesting to see her photo.

so is the DV 336SE OTL tube amp still a worthy option in this day and age compared to what else is out there? i can get it for $246.16 from a group buy. i plan to use it with my HD650. this will be my first real OTL tube amp aside from the Aune T1.

 

[Lorspeaker]

great combo to my ears... the dv336se + hd650. 
just roll in diff tubes for slightly diff sound,  FUN !
 
there is a La Figaro version/upgrade?, u seen that one?

might be worth the exxtrabucks.

yeah i saw a few posts about that amp while searching through head-fi. not sure if it's worth the extra $63 to $70 though when i add in getting tubes.

if u are just holding on to it for a year or two, then maybe the cheaper the better...
but if u are bend on keeping it for your grandchildren, the LaFig i supposed.
( i paid usd150 for mine...a 2ndhand set in v good cond )

I really missed my Darvoice 337. Seems not many people using it anymore.

If u are NOT buying the HE-6, this is absolutely the most gorgeous inexpensive tube amp u ever  need.. 

 
but of cos we hav WANTssss$$$.

Guys, for those who have heard both, not in meet condition. How do you think of the signature compared to the now 'in-(trend)' amp Crack with Speedball?

i'm looking into a 6SN7 tube to match with a JAN 6AS7 G Tube RCA NOS 1967 6AS7G (red text) i bought earlier. i'm going to pair it with the hd650. these are the choices i came across after reading this thread and the previous back and forth. can someone give a second input?
