6DJ8 / 6922 / 7308
6DJ8 / ECC88 is the "standard grade" of this family. They normally have steel pins.
6922 / E88CC is a "premium grade" version of the 6DJ8. Most have gold plated pins, but many Sylvania manufactured 6922's have steel pins (a few Sylvania's are gold pin).
7308 / E188CC is generally the highest quality tube in the 6DJ8/ECC88 family. Most have gold pins. Sylvania's are steel pin. They are designed with low microphonics and low noise. Sections are usually pretty closely matched.
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.
