If imaging/holography is also important there is really only one tube that does it all in my opinion:  the black glass round plate Tung Sol.  Most people would also mention the ECC32 here as well, assuming you can use it safely in your amp, but while it is a technically excellent sounding tube I never found it emotionally engaging in my setup which is just as important as the technicals.  This is why the Marconi B65 hangs out in my OTL a lot lately.  It isn't the best sounding tube from a technical standpoint, but it is the most emotionally pleasing one by far.

 

The best way to find your own priorities is to just taste test some tubes and then go back to what others have written and see how your impressions are lining up.

thank you Xcalibur255 for this helpful post ,... "black glass round plate Tung Sol" ..I have this one

Thanks for that Xcalibur255, when you say "sugar in your tone color" does that mean the sound is bright or is it sweet and warm?

Sweet and warm.  I was trying to avoid using the word sweet actually.  I'm fond of that descriptor, but it can be interpereted in so many ways.  Some people use "warm" to describe what I call "bright"...... that's the trouble with describing sounds with words.

You can also get the 6SN7W tall glass in a mica base.

Same as the metal base but much cheaper.

 

The short ones come in different styles I like the one where the lower mica is inside the base.

The 6sn7w is one of my favorites. Definitely a all arounder. Specially the metal base. If you see one with a cracked base dont worry, its pretty common among them. Of the 6 I have 3 of them has hairline cracks.

i've been thinking about getting a 6F8G to 6sn7 adapter and buying some 6F8G tubes. there should be no problems since they're the same from what i've read, right? this is the adapter i plan to buy

The 6F8G can be used with the adapter you have mentioned in a 6SN7 circuit without any problems.

Thanks Xcalibur255.

 

The tube I was wondering about arrived and looks like this:

 

 


 Does this mean it's one of your preferred Sylvania "GT" tubes?

 

Either way, I cant wait to give it a listen! I'm just waiting on parts to arrive for my Little dot MKIII adapter :)

The one Xcalibur mentioned has a taller bottle and a shorter base.

 

What you have though is a nice tube.

I have two Sylvania 6SN7GTs and two GTAs. They are all the same size and with the exception of the 1949 GT, they all have the same 3-hole plates and bottom mica. Perhaps my old ears and modest gear do not permit me to hear differences that others do, but they all sound the same to me. So my conclusion is short base, tall base, 2-hole plates, 3-hole plates, all these late 1940's / early 1950's heavily chromed Sylvanias are virtually the same tube, and they are different than my short-bottle 6SN7W.

 

GTs 1952 (left) and 1949 (right)

 

The 1949 tube has 2-hole plates and bottom mica similar to the 6SN7W.

 

 

Sylvania GTAs, both 1953

The number of variations Sylvania produced is absurd really.  There weren't any "clean" generations of designs in their tubes.

 

I look for dirty looking getter flashes now, with the hazy look that extends all the way to the plastic base.  This is the type of flash the old W tubes have and all the Sylvanias that have this type of flashing sound a cut above the rest to my ears.  I'm not saying the flash itself has anything to do with the sound, but my guess is they were all made on the same line or have more or less the same internal makeup and grid.

post #3972 of 4207
I'm not sure it's accurate to say there were not "clean" generations of design in Sylvania 6SN7's. They have many very commonly identifiable types. And remember Sylvania produced mass quantities of 6SN7's over a 40+ year period, which spanned the rise and fall of the vacuum tube as the primary amplification electrical device.

A pair of FIVRE 6SN7GT. I got these for a pretty good price as they are not quite a "matched" pair. The tube on the right has a side getter and the tube on the left, a bottom getter, but otherwise, they appear identical. In a quick search on Google, I wasn't able to find much of anything to help me date these tubes. An obvious guess is that the "7" and "6" might represent the last digit of the year, so perhaps, the 1940's or 1950's, or even the1960's? Can someone tell me a bit more?

Nice tubes, the one on the right is a GTA style with side getter.

I think they are 57 and 56 production.
