no longer for sale

Up for your consideration are 2 Made in USA Amperex 7308/E188CC pre-amplifier tubes. Painted date code is 67-40 on both tubes, which indicates 40th week of 1967. They are labeled as JAN 7308 (military spec) with globe logo and gold pins, and most likely NOS. These are the same tubes as Amperex Orange Label PQ 7308. These tubes have totally identical construction as Amperex USA White or Orange label 7308 PQs. Both tubes have identical construction. Tried on my preamp and they sound fantastic. Many consider 7308 the best of the best in 6DJ8 family tubes. Rated to have 10,000 hours. Test better than spec for new! Tightly matched (all 4 sections are within 5%)! Low noise! Guaranteed! I have 3 more of these tubes if you are interested. Paypal add 3.5%. *************************************************************************************************** Shorts, Gas and Noise: passed Noise Test: passed with very good noise and micorphonic characteristics Gm Test: Tube #1 Triode Section 1: 14300 Tube #1 Triode Section 2: 13700 Tube #2 Triode Section 1: 14300 Tube #2 Triode Section 2: 13800 Where minimum good is 7000 and 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.
