    nice! I picked up a NOS long black plate RCA 12AX7 from a junk store this weekend. $20... cheap for that tube but I expected it to be cheaper in this store... oh well. Win some lose some...

    I can't entirely tell from the photo, but the far-right one may be a Raytheon: are the plates shiny-black? Is there an oddly-shaped partial mica structure on top of the upper mica disk? Halo-getter? Yes = Raytheon.

    The "12AX7" lettering on the far left tube looks like a GE-style, even though it says "Tung-Sol." If it is GE, it's still very good, but not a genuine Tung-Sol.

    Hope they sound good to you. As long as they function properly, you'll probably enjoy them very much (no comment on the Sylvania, though).

    The one on the left looks like a GE. The one on the right looks interesting, may be an RCA... ones with plates like that usually sound great, but are often noisey.

    Nice Score. Those ge made tung sols are among my favourites in tweed and post tweed fenders. Nice jangly cleans. The Sylvania is a dark magical beauty. Deep mids with rolled off top end. The black plate is beautiful.

    Yes the far left is shiny black plate with that funny looking mica on top so I guess its a raytheon The "tung sols" look like my long plate GE's but the "getter" on the tung sol is mostly round with a flat side on the front of the halo.Is that what they mean by a "D" shaped getter? I guess the Sylvania is junk though...

    The real one is on the left. The one on the right looks like a GE.

    When it comes down to it, they're all real and good for something - it just depends on your taste and your amp(s). Personally, I favor the Raytheon black-plate for its superb openness/clarity, dynamics, and early-breakup into delicious overtones.

    Just tried them out quickly in my JSX V-1 and V-2 spots. The black plate is nice and sounds similar to the long grey plate RCA I have in there. Open and punchy overdriven I guess-I like the attack. The tung sols seemed smoother but Im used to the punch the RCA's deliver.The Sylvania as tybone mentioned is rolled off and would be good for a bright amp. Im still digging the long grey RCA's in the V 2-4 with a long plate GE in the V-1.The long plate RCA's seem to have more mids than the Raytheon or Tung Sol.Im gonna stick with the combo thats in there cause it just sounds tight,punchy and has a fat mid range(almost too much).I think the RCa's are my all around favorites for fattening things up while still being open or articulate. At 10$ a pop I feel like Ive done good!Thanks for all the info! Bob

    Gulp! I just noticed that two quads of Raytheon black-plates went for over $100 on eBay. Just last year, I was getting quads for less than $30. Zoiks!

    Hey, those RCA long gray-plates are excellent - you've got a good thing there, and I'd never question someone else's judgement after they've experienced the good stuff themselves.

    You've got good stuff. Its a little addictive, though, isn't it?
