Your rare chance to get a beautiful pair of New Old Stock (NOS) New in Box Made In USA Amperex 6922/E88CC PQ vacuum tubes with gold pins.
These come from a sleeve of 5 NOS Amperex 6922 PQ tubes I acquired years ago.
Never been used except for testing purposes.
They test very strong as they should, and all 4 sections are extremely tightly matched within 3%.
Very low noise and suitable for any application.
Tubes are fully guaranteed.
This pair has the same date code - 7L8*3B, indicating both are made in February 1963.
Even the sand blasted date codes at upper portion of the tubes (seen at the 2nd and 4th photo) are the same: 316 (16th week of 1963).
6922 tubes will have a longer lifespan than 6DJ8 tube.
In some cases 6922 tubes will last 5,000 to 10,000 hours vs 3,000 to 4,000 hours for 6DJ8 tubes.
Paypal add 3.5% fee.
Priority Mail shipping within US with tracking is $6.
USPS International First Class Mail is $12 ($10 to Canada).

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.
