Tesla E88CC/6922 - These are not the current production JJ tubes... NOS 1960's vintage, made in what's now the Czech Republic. Very cool, low microphony, loiw noise, and test very well. Airy highs, smooth mids, and great detail... never syrupy. If you are looking for a cool 6922 without spending big $$$, these are a great choice. It was very common to see this tube branded & sold as Valvo, Brimar, etc. back in the day, but the ones we have are all branded Tesla. Price is for a single tube.
Like most 1960's vintage E88CCs, these may "TING!" when you flip switches on your preamp, but that's normal.
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.
