6SN7GT VT231 TUBES

I'm using the Sylvania 6sn7 gtb tubes right now and love them. I actually bought several sets just to have backup. I also have a few sets of the Raytheon and Tung Sol 6sn7gt (not the oval mica). I think they are really close but slightly prefer the Sylvania. The Sylvania 6sn7 GT 3 hole Bad boys are a little bass heavy in my system but have great soundstage and some spooky holographic detail that I do love. I could certainly live with them.  I also tried the Ken Rad VT-231 clear glass but I have not found a set that wasn't microphonic unfortunately.  I'd love to try the oval mica TS VT-231 but those prices have just gotten too steep for me. Running $ 800.00 a pair etc. Wow!

I have heard that the military VT-231 designation is overblown and many of the standard 6sn7 GT or GTB from the same era sound no different. YMMV

Thomas,

I've read through your 6sn7 tube shootout many times. It's a great guide and has helped a lot in my selection. Any particular 6f8g tubes that you prefer?

Thanks,

Mark

One of the best things about the 6sn7 tubes other than they sound great is there are still a ton available and many at reasonable prices. I use them in a Modwright LS 100 preamp. I didn't go all in on the Tung Sol round plates that go for such high prices but I have a nice selection of Sylvania, Raytheon, Tung Sol, and RCA that should take care of me for many years. I much prefer those to any newly made tubes I have from Russia or China. The somewhat standard Sylvania 6sn7 gtb sound very good in my system and they are plentiful.
