Sylvania 6SN7WGTA - Wonderful open tube with superb extension top and bottom. These are in military JAN boxes made in the 1970’s, and are excellent examples of when Sylvania really mastered how to make this tube. No driver grade in stock. We grade them one by one in a simulated phono stage, and listen to them with headphones. So when we say low noise, low microphony, we mean it. Fabulous Gold and Platinum grade for the pickiest positions.

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.
