Have you tried both? Thx.

Yes couldn't hear any differences. Haven't tried the unobtanium Brimar 13D2 though, that is supposed to be a different beast.

Couldn't tell you, as all markings were removed. I think I can detect a faint presence of red in spots, but can't really tell. It was purchased forma recommended HF seller. The structure of the tube seems identical to the red lettered ones I've seen pics of -- round bottom mica | Top round spike mica, dual round ribbed plates.

Can you post a couple of more pictures (i.e. the top of the tube)? Thx.

I believe is the one you have.

Will do when I get home.

Yep -- mine look like the tubes pictured. My plates look much darker however, but it is likely the lighting or camera flash used with the Tubemaze pics.

I tried to see through the smoke glass of a CV1988. But the glass is so dark. I find it has welded plate (grey round), and a O-getter at the bottom.

This is 100% a Brimar. I believe it should sound same/very very close to a high priced black glass one.

Excellent!! Nice to have confirmation that it is legit since it is my 1st Brimar 6SN7 tube. Thanks!!

Another interesting thing with the Brimar tubes, is that the black glass came first, but has a halo or ring getter. The clear glass came latter, but has the d getter. It is usually the other way around, with the d getter, on the earlier tubes.

Those sure do look like black plates. . .and I think there are actually a couple more variations of this tube, than listed. For example grey vs. black plates. However, every review, I have read, on any of the Brimar 6sn7gt, seems to be very similar, so I don't think you can go wrong, with any of them.
