From Russia with love. These current production tubes are quiet, they sound great, and are dependable... giving them Uncle Kevvy's seal of approval. A great choice for any 12AU7/ECC82 circuit.
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 - Not available for this tube.
If you have a preamp or phonostage, you need at least Gold grade.
