Rob (Skylab) sent me a high resolution jpg of his tube closet and I had the puzzle made. It is pretty good quality.

David was kind enough to send me one, but I haven't been bold enough to tackle it yet biggrin.gif

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.

That's very nice David!

But you haven't finished yet, you must stand the right tubes boxed on top of the puzzle............

Due to Rob's kindness I actually have a half dozen of the boxes in the puzzle in my possession.

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).

Not sure but the Canadian GE 6SN7WGTA's are super nice tubes. Real sleepers. Very balanced sound, just slightly rich but also with a touch of very attractive top end sparkle.

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

Go by the physical structure of the tube internally. There was so much variation in labeling you cannot trust that. In the case of hytrons you can also go by the etched ID marking on the top of the tube. The circle around the 6sn7 mark is pretty unique to hytron.
