Realistic Lifetime Japan ONE (1) 6JS6B Beam Pentode Compactron tNOS TESTED Vacuum Tube Yaesu FT-101 6LB6 Beam Pentode Audio 1973

This listing is for One (1) 6JS6B Beam Pentode 6LB6 Beam Pentode Compactron vacuum tube in the Straight-walled Glass tube shape. It has a 12-pin T-12 base, grey plate, and dual or quad halo getter.

Your tube has been fully tested on our B&K Dyna-Jet 606 tube tester with like new, NOS results (tNOS). Here's what that means: to qualify for this listing, several stringent conditions must be met: the emissions for each section must test within between 80% and 120% of bogey values, consistent with original 1973 RCA, Sylvania, GE, and/or Tung-Sol datasheet specifications for new tubes of this type. The tube must also show no shorts, no open elements, and no measurable heater-cathode leakage. The tube might have mechanical wear or have the label rubbed off - these are very old! Unbalanced and used-testing tubes are available in a separate listing at a significant discount. Every tube you receive from Sound By Doc is guaranteed against failure for 60 days after purchase, an industry extreme!

Most of our tubes are tested with one of our Amplitrex AT1000 tube testers, but these fantastic testers do not have built-in support for this tube type. Therefore, this type is tested on our Dyna-Jet 606 tube tester from 1966. The Dyna-Jet is well known for its excellent Grid Leakage test. Since we have not calibrated your tester, we cannot guarantee that the test results on your tester will be the same.
