That is true.

Thanks.
You are a good teacher, I am learning fast.
 
BTW it sounds very nice, it has copper posts, grey plates and a very strange looking wire getter.

Now that you've said it, I see copper as well in my r93 L1E, and a D getter.

How does it sound?
What brand is it?

 

[Oskari]

It's the Miniwatt I've mentioned before. It's been growing on me.

Is there a grail 6SN7 or Sylvania ?  I thought the metal base Sylvania 6SN7W might be the grail because of its price.  

Yes and no.  I spent the better part of a day auditioning some of effusions33's  rare and classic 6sn7s in a simple La Figaro amp.  It all depends on which tubes are going to be used with them and what headphones you use.  It sure is fun hearing all the different "flavors"  of 6sn7 though.  I got to hear several Sylvania 6sn7wgta, the Tung-Sol round plate, NU and RCA black glass, Hytron, Mouse Ears, and Bad Boy.  I can honestly say with some setups some of the more rare ones did not gel as well.  Lots of fun for sure.

Have you got photos to share?
 

 

[rosgr63]

To me there are two types of 6SN7 grail:
 
Those which are rare to find and sound great.
 
Those which are very rare to find but sound average and are nice for collection.
 
IMHO those 6SN7 which sound great, are easy to source and do not cost a lot are the best choice. As bixby said above it's all about system synergy.

Here is a photo of the tube, I'll get one of the getter soon.

Can anyone provide more information on this tube ?
It's a Sylvania 6SN7GT, 3 hole plates with extra 2 holes behind each plate. 
 

 
 
 

 

[rosgr63]

It looks like a GTB type tube.
The plates are at an angle to each other right?

 

[Audio-Omega]

Yes the plates are at an angle to each other.  Is there anything special about the tube ?  Do you know what's the year of production ?

 

[Skylab]

Very common Sylvania tube, likely somewhat late production, could be anywhere in 60's or even 70's, I think.  I have some JAN-CHS 6SN7GTB's with the same plate structure that were made in 1979!  I actually think they sound quite good, and can usually be had NOS for very attractive prices - like $15 per tube.  IMHO, worth stocking up on at those prices...someday soon even these will not be easy to get...

 

[rosgr63]

I like GTB type tubes, but some people don't think much of them.
Is there a date code printed on the base or glass?
 
I think the GTB's appeared in the mid 50's.

 

[Audio-Omega]

There is a C5B or C58 printed on top of the glass.  It might be a late production tube because the inside looks new and shiny.  

 

[Audio-Omega]

It sounded very much like the other Sylvania (6SN7GT 1949) except it had a harder sounding treble.  Low end bass was missing in the first few minutes of listening.  I should give it for a few weeks to burn in.
