Matched pair of NOS E88CC/6922 tubes made by Siemens in West Germany.
I obtained these tubes as NOS without their boxes and they test exactly like NOS and look NOS too.
Both tubes have red color painted dots indicating special selection (medical application, etc).
Both have identical construction.
Etched codes on metal inside of tubes: A4 8J
Made in 1968.
Tested in my preamp and they are super quiet and extremely strong!!!
All 4 sections matched within 3%!!!
I have 3 more of the same tube if interested.
Paypal add 3.5%.
I guarantee excellent performance, so buy with confidence.
If you are not satisfied with my tubes for any reason, just let me know and simply return the tubes for full refund.

All tubes are tested by Hickok 539C vacuum tube tester. This tester was precision calibrated by Roger Kennedy to improve measurement accuracy. 83 and 5Y3 tubes were replaced by Solid State rectifiers to minimize calibration drift in the tester.
All tubes are installed into an actual audio circuit to screen them for internal tube noise/micorphonics. This is especially important with the 6DJ8/6922/7308 tubes.
Music Reference RM-4 pre-preamp (moving coil head amp with 30 db gain) is used for "in circuit"/real world noise/microphonic testing. This unit uses two 6DJ8/6922/7308 vacuum tubes. Each channel uses both triode sections making it ideal tool for noise/microphonic testing of both triode sections.
