This listing is for two (2) WWII Ken-Rad NIB military 1625 audio tubes that test NOS on our Knight 600A tube tester. They have also passed shorts and gas tests on each section. The photo is our stock photo, but your tubes and boxes will look almost exactly the same. The Ken-Rad tubes feature L bottom getter, mica spacer wings, brown base, and black plates. Boxes have a wonderful 1940s patina and some crumbliness.
Brands we have in stock include RCA, NU, Hytron, Ken-Rad, and Sylvania. They can be found in separate listings.
Tubes that test new but are missing boxes are available in a separate listing. Used tubes are also available in a separate listing.
Most of our tubes are tested with one of our Amplitrex AT1000, but they do not have a built-in 7-pin base socket. Therefore, these are tested on our Knight 600A tube tester from 1969. All tubes are guaranteed against failure for 60 days. Since we have not calibrated your tester, we cannot guarantee that they will test the same on your tester.
