Mullard 6201 - This is the gold pin version of the CV4024 ...they seem to have a little more zip on top, and a smidge more bass extension.
This, along with the military CV4024 are the most popular 12AT7 types we offer. This is a much better choice compared to the Amperex as this particular Mullard sounds better and will last a lot longer. We also have some of the earlier Mullards and Amperex with folded over plates but they never test as well or last as long.
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.
