Ha! I knew I wasn't crazy. The second I saw it I thought "that looks like the photo of Rob's tube closet."
What a cool idea.

Any opinions about Canadian Marconi 6SN7 GTB as output tubes for a DIY amp for Stax 009? The amp sounds great to me, way better than with the Sovteks that were in it before (not surprisingly).

Hi
How different are the CBS red label GTB's from the GT's? Turns out the seller tagged the tubes as GT's but upon closer inspection of the pics, they said GTB's. Similar in most other aspects except for the bottle being slightly shorter. the top circular label says GT though.

They appear the same structurally to me so you should be okay. After a point the Hytron tubes became rebrands when Hytron themselves were absorbed into other companies. Yours are still Hytron made judging from the photo. I suspect there would be little to no difference between them and an older GT version sound wise.
Yes, they do look the same but it is all very confusing. I read elsewhere (i think on the Reference thread) that only the white labels are Hytrons. The red label CBS GT's and especially the GTB's are relabelled GE GTB's which sound ordinary.
Thanks
