Sylvania Gold Brand 6SL7GT - Very cool, super rare vintage 6SL7s made in the U.S. by Sylvania. After we evacuated most of our bulk tube inventory back in 2002 due to the fire that came very close to our shop, some cool stuff got mis-placed down at the warehouse. Well... I just had the guys go through everything, and they brought back some cool stuff I completely forgot we had! These Sylvanias are extremely rare, and we only have a few, so they will go fast!
Platinum grade - The best of the best. Lowest noise and microphony with the tightest triode balance we have available. This is typically 10% or tighter, but may be higher depending on available stock.
Gold grade - Low noise and microphonics with a triode balance typically between 15% and 20%, but may be higher depending on available stock.
Driver/Buffer grade - Lowest noise but not the lowest in microphony. Triode balance will be similar to Gold grade.
This grade is only suitable for use in the driver stage of an amplifier, or the output/buffer stage of a DAC or CD Player.
