Thanks musicman.  What is the life span for these tubes?  I am getting a pair soon, I will campare them with TS 6SN7 BGRP in my WA22.  Does the 6F8G sounds very similar to TS 6SN7 BGRP?

I bought a pair of used ones with good readings from a fellow member here for $165.

I also have one pair of round plate black glass Tungsol 6F8G VT99 early version
which cost around that range.  I prefer that to the sound of the Tungsol BGRP 6SN7's.
I also have the Tungsol 6SU7GTY  round plate recommended by Stavros.  All those
3 Tungsol's are excellent and I found that the 6SU7GTY  works wonderfully with the LCD3.
They are VT99, military version so the life should be longer.

Does this refer to their use in your ECBA?  Do we need an adapter for 6SU7GTY?

Did you buy the pair from 'danska?' If so, I might as well climb off the fence...

    Yes I am using them in my ECBA without any problem.  They are like the Tungsol 6SL7's
so no adapter needed.  The Tungsol 6SU7GTY is a premium grade of the 6SL7's.
At the time of the recommendation the cost of a NOS pair was much less.  I could  also
get the Tungsol VT99 NOS at a good price.  Now the Tungsol 6C8G NOS pair is coming too,
this one is like the 6F8G's so they will need the 6F8G/6SN7 adapter and the gain is between
the 6SN7's and 6SL7's

The range of prices on ebay on what seem to be the same tubes is crazy.  We need to organize and agree not to pay ridiculous prices in an attempt to bring them down! 

 
Discounts--
 

 I'm with you! The communication here is great. And at some point, some sellers may want to move a packaged lot at once and be done with it. But they should be willing to pay for that privilege of doing business with us as a group!

Kiertijai, Thanks for the information.  Is VT99 the military version of 6F8G?  I suppose they should be of higher price than normal 6F8G.  I now have a WA22 to drive a balanced pair of HD800.  I am thinking about ECBA, but hesitated because there are several owners commeted that ECBA is not the best with HD800. 
 
To get off topic a little bit, I read that you perfer 007 over 009 for romantic classical music.  Does that remain true?

    Yes it is. It is supposed to be more expensive but that's not true in my case I can get the Tungsol VT99 and National Union VT99 at around 150$/ NOS pair
 
there are several owners commented that ECBA is not the best with HD800. 
   I think the ECBA can drive the HD800 very well however it does not help improve the soundstage
of the HD800 because the soundstage is already very good.  What the HD800 lack is the bass which can be improved my some modification as described by Purrin, recable with cable like apuresound, blue dragon or Zeus cable, tube rolling with Kenrad to improve the bass response.  You may also consider the Super7 (which use one 6SN7 as driver and 6 6SN7's as power)  , this amplifier has been reported to drive the HD800 very well may be up to 80-90% of the BA with the cost at 1500$ (introductory price) as use the warm tube sets as proposed by Purrin and Anaxillus.
 
 I read that you perfer 007 over 009 for romantic classical music
   I don't remember those comments.  However I have compared the HE90 with the SR009 and I think I prefer HE90, SR Omega more than the SR009.  The SR009 is an excellent headphone however because it is more forwarded and quicker pace with narrower soundstage so I prefer the HE90 more.  I do think the SR009 is more suited to sweet classical music from Vivaldi, Beethoven early, Bach but for Tchaikovsky, Brahm , Mahler , Gorecki which are more dramatic , more complex, more dynamic I prefer the  HE90.   Some of the Thai head-fiers prefer the O2mkI (007) more than the SR009 driven the DIY T2 as they think the SR009 may be too bright and more fatiguing.  However it depends on the amplifier used as one member said that the performance of the SR009 is better with the use of Woo Wes max.

In WA22 the best combination for me with HD800 (with a pair of DHC complement balanced cable) is a tie between Tung sol7236/RCA Vt99/596 and Tung Sol 7236/TS 6SN7 BGRP/596.  Both are better than those repalcing 596 with EML 5U4G.  The 596 is a shocker to me, add base to HD800 while improving soundstage and weight.  To my ears they are better than EML 5U4G.  
 
Who sells super 7 now?  I thought Criag has closed the introduction run.
 
I love my 007, right now I am using a Stax 007tII with an audio-gd phoenix as pre-amp.  Only 007tII is not good at all.  I am very satisfied with the sound, but I am waiting for a BHSE in the 45 batch.  Actually, the Thai head-fiers' comments make me worry that 009 may be a completely different game.  My WA22 has a pre-out, one possibility is to use it as an pre-amp to warm up the BHSE.
 
Do you think 009 and HE90 both are much better than 007 for classical music?  I feel that impactful base and dynamic is critical for orchestral music. To my ears, 007 sounds much closer to a real life concert than HD800, although the latter is more stunning in certain ways.  I listen to violin a lot, which phone is the best for viiolin?

 I am not sure about the life span. I have a pair of the 6SN7 BGRP too. The sound is very similar and I personally prefer the 6F8G.

Thanks.  I check it by google.  What information I have suggest the life span are in several thousands if hours.  I am getting a pair of TS 6F8G soon, very excited.   

 

[Blackmore]

Life span of say 5692 RCA industrial version was stated for 10.000 hours. If you want the tubes that have longer life, you need to buy them from the very trusty source, 100% NOS, fully tested and military/JAN versions only. Other than that, you will never know.

   I think all the 3 mentioned headphones are excellent and it comes down to personal preference.  I don't think you will have problem with the orchestral music.

Thanks for your comments on and for sharing your wisdom of the tubes and phones.  I could not wait to try the TS 6F8G.  Hopefully, someday I can have an opportunity to check out the HE90.
