The 6sn7 tube is often used as a driver tube for the output stage of many amps. They are used as drivers in my Rogue Audio Stereo 90 amp. As I have long collected this tube,wanted to get an idea of what others are using and try to come up with a consensus on the best 6sn7 drivers.
My favorites (in order of favor):
1. 1952 Sylvania 6sn7GT bottom getter (often called "Bad Boys")
2.Russian metal base "hole-plate" 1578
3. Sylvania 6sn7W black base (have not tried the metal base)
4. Raytheon VT-231 flat black plates mica support rod
5. Tung Sol 6sn7 GTB tall bottle horseshoe getter
6. Sylvania VT-231/ Sylvania 6sn7GT bottom getter
7. RCA 5692 redbase
8. Sylvania 6sn7WGT brown base
9. National Union black glass
10. RCA VT-231
For comparison, my least favorites:
1. Sovtec 6sn7
2. Ken Rad 6sn7gt clear glass
3. GE 6sn7GTB
4.EH 6sn7
5. Sylvania 6sn7GTB yellow or red lable (latter production---the earlier green label GTB's are OK)
6. Sylvania 6sn7GT top getter (much prefer the bottom getter Sylvania 6sn7GT from the 1950's)
Opinions?
