    Lol.. Right on.. We're gonna have to trade tubes in the near future,.. Nice !

    Well, not sure if I should be upset or just ok about it, what I thought was gonna be a pair of GE tubes turned out to be one GE tube and one DELCO tube.. Both 6SN7GTA. O.o Anyway the description said side getter and It didn't phase me till I got them, most tubes, that I know of, have them on the top and bottom, on the side? This is my first set of tubes like that.. Kinda stoked about it in a nerdy way. :D
    Warming the GE up as I'm typing this and will edit my personal thought on sound later tonight.
    EDIT: vocals here are a little sweeter. Maybe because of the small forwardness? Need to sit with these for a bit (week) to get a true sense of what I'm hearing :)

    These are the three I got today
    GT,GTB, and WGTA

    The gtb and wgta are almost identical build wise. Wgta is taller, thats the only difference i can see. Sound wise i cant tell them apart.

    All three pair pretty good with my rca 6as7g.
    Should have a sylvania 7236 and sylvania 6sn7 here thursday.

    Just popped a GE Jan 6AS7 in. Really happy with this compared to the RCA Jan 6080. Seems more responsive and dynamic. I've been going back and forth on the 6sn7 but I keep going back to the GE GTB. Is 61-43 the date code on those?
  6. JKDJedi
    Yes, my uneducated guess is 61 weeks into 1943.. Can you show us a pic of it?
  7. JKDJedi
    Takes about a week before settling in..give em time, nice collection!!

    I also have another with the date code 59-13 which has red dot on the bottom.

  9. GEK
    1959 & 1961

    Nice side getters there.. yes so the 188-5 means it's USA made GE, and the 59-13 means 1959- 13th week. Same for the other numbers.. 1961 43rd week.

    Great, that's what I figured. I'm glad to have two, I really enjoy this tube.

    I've sort of gone a little crazy grabbing 6SN7 tubes and tried all of these, some only briefly though:


    The last one on the right is an RCA.
  12. JKDJedi
    That Westinghouse.. U Like? Whats your impression on it?
  13. Ad720
    I do. That was the first one that landed and I spent a little time with it before the first of the GE GTBs landed. I feel like it was a little grainy compared to the smoothness of the GE but along with that came a bit more punch.

    The silvertone was a big surprise honestly. That is a very punchy tube, very full sounding. I'm not crazy about the Tung-sol, also a surprise. I haven't spent much time with the mystery RCA or the National (I believe that the national is a rebranded GE but I'm not sure). I need to give the Sylvania a chance as people seem to really like that one. It's just hard.to take out the GE right now .
  14. JKDJedi
    Yeah, I wasnt overly excited about the NOS TungSol the same, however..the NEW (russian made) Tung-Sol.. I like, I also have a Westinghouse and dig the crazy width it has. And yes, the GE I just got is staying in (for now, swapping power tubes for best match ). And thanks for the heads up on the Silvertone. What numbers does that have? Usually a give away on who made it for them.

    edit: found it! it's a Sylvania. https://www.worthpoint.com/worthopedia/sylvania-silvertone-6sn7-tube-vintage-111579344

    I use a 6AS7 Winged ”C” bought from the thetubestore paired with Tung-Sol 6SN7 GTB.
    Before buying the amp I was afraid that the experience will be disappointing. My original purpose was to find something to tame the akg k812`s harsh upper mids. Because I had doubts about the pairing with a OTL Tube amp I decided to buy something on the cheaper side, hence the darkvoice.
    I have to admit that I was VERY pleasantly surprised. It does work exceptionally with the akg and also with the planars (oppo) though I have to say that I prefer the pairing with the dynamic cans (although mine are low impedance - 36 ohms).
