For sale is one pair of 6922/E88CC tubes, by Siemens of Germany for RCA.These are the holy grille of tubes when comparing to all the E88CC/6922/6DJ8/ECC88 tubes.I was fortunate to save these few pairs for my memorabilia when I left the SP/AR in the mid 1960s. SP/AR (Special Products & Applied Research), was later called SPAR Aerospace Co. in the '70 and later. They had a few projects going on in those formative years, including the CANADARM, BOMARC FUSING systems, AND INFRA-RED DETECTING units, to name just a few. The E88CC's were used in the most high tech expensive instruments.When the E88CC's were introduced into the North America at that time, all the instrument makers jumped on the wagon to use them in their most expensive instruments. The average grade instruments were equipped with the cheaper 6DJ8's. In those years, one high tech scope cost about $2000 to $3000. That was about half a year of an engineer's salary. And yet, there were only two such expensive tubes available in each instrument.That's the reason I call these the holy grille of tubes with justification.Tubes were made by Siemens in Germany. These are the most prestige tubes available to day in its class, with gold pin, special filament winding, chrome shield between the dual triodes.The Siemens codes (on the glass bottle): ‡8F, and too faint to read on the other tube. Exact ratings on both sides. These tubes were computer-checked for exact details prior to installation...Test ratings: 108/105 and 105/105 on my Jackson 648s tester, minimum at 70, new tubes at about 105.
