Thanks X.
 
Have any of you guys tried 5694s (with adapters) in place of 6SN7s?  Some guy is selling a quad for $1000 on audiogon.  Skylab was kind enough to point out that Brent Jessee has them for $14 each.

Hmm.  Neither of the places I go to look up datasheets has one for the 5694.  Is it a variation of a 5692, perhaps a 12V heater version or a different base/pinout?

 

[Skylab]

No, it's a 6.3v medium-mu dual-triode with somewhat similar specs to the 6SN7, but not identical. Closed to an ECC32, but not identical to that either. Also the pin out is different so an adapter is needed.

Thanks for the link.  An interesting tube, especially the big ST-14 glass.  It would probably work in my amp, though I noticed the plate current is a little lower than the nominal 9mA the 6SN7 is run at in mine.  Probably not enough to strongly affect longevity but I'm sure it affects how it sounds.

Sorry guys, could you do me a favour and help me choose the best 6SN7 tube from the list? I would greatly appreciate it.

[size=small]All of them are some kind of 6SN7GT. I have chosen them because they are in range of 35 $ in the shop that I'm going to buy.[/size]

[rosgr63]

They are all nice tubes for the money.
I would start with the Raytheon Large Black Plate.

 

[Skylab]

Those are all nice. I agree with Stavros about the Raytheon, and on that list I also really like the tall bottle Sylvania.

I'm looking for tubes for a La Figaro 339, I guess the same recommendation applies?
 
@NoMatterWhat: Wanna PM the link to the vendor? Tx,

One thing i will say to you is that all these tubes are ok, but it will come down to what you like, what your ears feel is a good sound to you, by all means go off suggestions but it comes down to your own tastes. One thing i will say i have had tubes not sound good in amp X but sound fantastic in amp B, so i am trying to say that peoples opinions are a guide as to how they found that tube to sound at that point in time.

One has to start somewhere.
Unless one tries for himself they will never know.
As many people have mentioned before it's all about synergy and personal preferences.
However some general rules are valid.

It's really hard in the beginning. All these different combinations of letters and numbers that are the "same type" of tube.
 
Any tips for a DarkVoice 337/La Figaro 339, listen to bass-heavy music (and actually find the HD650's bass-light)?

 

[rosgr63]

Valentin it's not that difficult really.
There is one basic tube the 6SN7GT, the rest of the letters and numbers are some specifics that should not worry you that much for now.
If you want to learn more when you have time check the 1st post where I have mentioned some reference threads.
Try the Sylvania 6SN7GTA, or National Union 6SN7GT black glass, what's your output tube?

You are aware that there are no 6SN7's used in that amp, yes?

 

[rosgr63]

Thanks for pointing it out Rob, I wasn't aware of that. 

 

[dminches]

Stavros, you almost blew up his amp !
