6922 / E88CC is a "premium grade" version of the 6DJ8. This tube is made by CBS and has gold pins. It tested at 9500/9500 micromho
This 6922 tube type was rated the "best buy" by Vacuum Tube Valley magazine in their 6DJ8 / 6922 tube shootout. They cited a better bottom end and "less offensive" high frequencies as two of the reasons for their choice. This is also the same tube which is sold by Richardson's under the Bugle Boy brand name.
This 6922 tubes is specially selected and has to meet our tough standards (less than 50% pass) for low noise levels, which guarantees the best performance for preamplifiers.
Special note for owners of the Audible Illusions Modulus 3 Pre-amp: this tube will not work in this pre-amp. We haven't seen any other pre-amps that experience the same problem (extreme sensitivity to microphonics).
The 6922 / 6DJ8 tube type is equivalent to the European ECC88 / E88CC tube and can be used in any 6922, 6DJ8 or ECC88 circuit.
