Dear adhoc, the Sylvania 6SN7W tall bottle black base(6sn7 W B 5 stamped on top of tube), better than the Sylvania 6SN7W tall bottle metal base(6SN7 A L 4 stamped on the top of tube)? I have a Sony Modwright SCDXA5400ES that i would like to tube roll.

Recently got my hands on the new Psvane CV181-T and one thing is certain... its not a relabeled Shug Treasure.  Not even remotely similar.  The one I have is very clean, with great deep bottom end and extended treble without being V like.  Not a cheap tube and I could definitely do without the gold base but so far so good.

My Sylvania 6SN7W brown base finally came in and wow, just wow.  The Ken Rad might have been the goto for bass heads but I'm glad mine was smashed and I tried the Syl instead.  Its not neutral, its not terribly clean, but damn it's musical with a great bottom end.

Need help on this. its my favorite and cant identify it. It is labelled Micro Electron. Its a 6SN7GTR. The plates are pretty long and has a square getter.

It's actually a 6SN7GTB (the last letter is a B, not an R). And to me it looks like Raytheon.

I think it might be Sylvania.  Could be wrong.  Do you see any teeth on the mica?  Most Raytheon I've seen have those spiky teeth on them.  Also look for the numbers of holes on the plate.

Hi, need some help.. I just acquired 2 Sylvania 6F8G VT-99

I installed them into woo audio adaptors and then into a Yaqin tube buffer.(SD-CD3)
I noticed that the filament glow in one of the tubes is more then the other. In the middle part. Is this because maybe the black coating in the tube may be not exactly the same.. ?Thus allowing less glow to show...?
Or is there a problem with the filament and should return them to the seller...?

I did get some inference noise, on first power up, on the side of the tube with less glow...
And then a few random loud pops... On the same side. I immediately turned off everything.


Any help from some experts would be great

Regards
Max

So many to choose from............

Post all the markings on the tube it will be easier to identify, from what you have there it looks like a Sylvania.

Can anyone confirm for me that this is indeed Tungsol 6F8G round plate?
