I have many Amperex 7308/E188CC and 6922/E88CC vacuum tubes with Gold Pins for $95 per each tube.
These are labeled as USN-CEP or USN (US Navy) or JAN (Joint Army Navy), indicating they are made by Amperex for US Navy and made in Amperex manufacturing plant in Hicksville, New York.
These are exactly the same tubes as highly sought-after Amperex White Label PQ 7308 and 6922 tubes possibly with tighter and more stringent military spec than PQ's. All of these are made from 1962 to 1966 (white label changed to orange color label from 1967).
They have etched code of either VR (designation for 7308 tubes) or 7L (designation for 6922 tubes).
These came from military equipment which should be barely, if ever, used based on measurements and listening test in my phono preamp (Music Reference RM-4 MC Head Amp). They test very strong like NOS, and should give you years of trouble-free service.
All of these are PHONO GRADE (very very low noise/microphonics) and suitable for all applications including Phono Stage/Line Stage and, of course, Driver Stage.
Since I have many of them, I can easily select matching pairs/quads, etc. Simply ask if you need 7308 or 6922 tubes and the number of tubes you need. I will send you photos of selected/matched tubes with actual measurements.
Quiet, Dynamic and Warm. Many consider Amperex 7308/6922 White Label tubes to be the best of the best in 6DJ8 family tubes. Rated to have 10,000 hours useful life!
I guarantee excellent performance, so buy with confidence. If you are not satisfied with my tubes for any reason, I will issue full refund for your purchase price.
