GE 6SN7GTB In white box, absolutely perfect 1960’s 6SN7GTB. These have a helically wound filaments and are very low in hum. Open and airy top end. Absolutely pristine stocks. Beautiful Gold and Platinum grade available, suitable for the pickiest phono stages and preamps.
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. Price is for a single tube.
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.
