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.

The ECC 803S (ECC803S) Telefunken Gold Pin High Mu Twin Triode tube is RARE and difficult to find.  The ECC803S is a very low noise, special quality 12AX7, made with the old-style Telefunken German precision. These have the ultra wide bandwidth of the Telefunken ECC803s, but also have nicely matched internal triodes, gold pins, and have been carefully factory-screened for low noise.
