Amperex 6922 White Label test strong in box [Expired]


no longer for sale

Up for your consideration are 2 Made In USA Amperex 6922 vacuum tubes with gold pins. My most favorite 6922 tubes! Test strong! These are exactly the same tubes as Amperex White Label PQ 6922 tubes, but PQ Logo is missing. Hart to read dates codes, but I am sure these are made in early 60's. 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. Tested for noise(quite), shorts and gas, GM reading is very good and exceed or close to spec for new. (Possibly NOS) Tube #1: Triode Section 1: 14000 Triode Section 2: 14000 Tube #2: Triode Section 1: 13300 Triode Section 2: 12200 Where minimum good is 7000 Value for new tube is 12500 I guarantee excellent performance, so bid with confidence. If you are not satisfied with my tubes for any reason, I will issue full refund for your purchase price. Buyer pays for return shipping (no returns so far). Priority Mail shipping within US with delivery confirmation is $5.90. Priority Mail International Small Flat Rate Box shipping is $13.45. First class mail will cost less. I can ship by First class mail if requested. 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. I also perform listening tests on these tubes using Music Reference RM-4 pre-preamp (moving coil head amp), which has 30 db gain. This unit uses two 6DJ8 tubes (one for each channel). Each channel uses both sections of the 6DJ8 tube.
