6SL7 tube - need a great pair - Page 2

post #16 of 19

The only comparison I had was against the NOS Russian 6H9C black base short bottle that came with the amp.  It was a lot better than the Russian, but that might not be saying much... :)

I got 6SU7GTY(6SL7) Black glass Brown base from eBay last week with brand OWL on base and 6SU7GTY on glass.

Just curious who made this tube? as far I know only Tung-Sol made 6SU7GTY Black glass.

Skylab,
Thanks for checking
I put this tube in my SET 300B amp as input/preamp , the result not impressed. I prefer my Silvania VT-231/6SN7 (my amp can use both type), more musical an relaxed.The gain of 6SU7GTY give better on bass only.
So, I will stop looking for 6SL7 and explore 6SN7/VT-231 world... starting with RCA 6SN7 Smoke glass probably.
