Brimars are very sweet, lush sounding tubes. [] It should be noted that Brimars are also the quietest 6SN7. All in all, the CV1988 is a terrific tube. You turn to Brimars when you want a more euphonic sound. Strong bass, wide midrange and soundstage.

these kenrad black glass 1940's tube have great bass, drive, sweet midrange, good bandwidth. Bass is definitely it's strong suit. On the other hand, the highs are more grainy then other tubes.

slightly below strong on 1 side of that 1 tube, but no effect on the sound, the test results show they should last for many years, at a bargain price

Extended highs, a crystal clear midrange lacking some of the Sylvania's warmth, and an extended bass response. level of detail seems higher than it is with Sylvania's, and the bass impact of these tubes really comes through. are much more forward in their presentation

Quiet and musical, the best of the non-military tubes, most mellow and have the most refined sound. Very smooth and airy up and down with a nicely detailed high end

this might be one of the finest 6sn7. very detail, good mid vocal. beat some of the highly rated 6sn7.

tubes are tested on tv-7 tube tester use by U.S army and airforce where minimum good for 6sn7 is 50/50. strong start around 85/85
