Up for your consideration is one pair of Amperex ECC88/ 6DJ8 pre-amplifier tubes. These are made in legendary Holland Heerlen plant in 1961 and 1960. They have large O ring getter (opposed to small o ring getter), which indicates sought-after earlier production ECC88. They are among the most musically enjoyable and engaging tubes ever made, and known for natural midrange with huge soundstage, three dimensional imaging. They have great dynamics including excellent bass/mid bass punch and are always musical. Tese Amperex 6DJ8 tubes will be a great upgrade for your tube equipment. One is bugle boy and the other is labeled as HP, but they have identical construction. Shorts Test: Passed Gas Test: Passed Matching: 15% for all 4 sections Listening Test: Very good noise characteristics Gm Test: Both tubes test NOS with no issues. Results are as follows: Tube #1 Triode Section 1: 13500 Triode Section 2: 14500 Tube #2 Triode Section 1: 12600 Triode Section 2: 13000 Where minimum good is 7750 Spec for new 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. 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.
