Bendix ONE (1) 5852 tNOS TESTED Vacuum Tube triple mica 6X5GT premium Audio 1938-1961

This listing is for One (1) 5852 6X5GT premium vacuum tube in the Straight-walled Glass tube shape. It has a micanol octal base, black plate, and dual D getter.

Your tube has been fully tested on our Knight 600A 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 both sections must test within between 80% and 120% of bogey values, consistent with original 1938 RCA, Sylvania, GE, and/or Tung-Sol datasheet specifications for new tubes of this type. The tube must also show no shorts. 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!

These photos are not stock photos. You are looking at the actual tube you will receive. Serial Number L-0812.

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 Knight 600A tube tester from 1969. Most vintage testers use a proportional emissions test at 30VAC and extrapolate to real, working voltages, but not this one! The Knight tester is revered for its 250VAC, real-world emissions test and for its robust gas test. Since we have not calibrated your tester, we cannot guarantee that the test results on your tester will be the same.
