Mullard 12AU7/ECC82 - early production old logo Mullard with the regular plate. 1960's vintage new old stock. Though they say they're made in Great Britain, this tube was actually manufactured in the Mullard factory in India. Still a fantastic tube and delivers that glorious midrange you'd expect from Mullard.
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.
If you have a preamp or phonostage, you need at least Gold grade.
