    I'm wondering if there are any good American 12ax7's for High gain amps? I know the European 12ax7's such as Mullard's, Brimar's, RFT's and Tesla's s sound great for high gain amps but how do RCA, Sylvania, GE etc. sound?

    All the above you mentioned are fantastic. My personal favorites include RCA Blackplates and Greyplates, GE, Sylvania, and JAN Philipps. I use all these in various amps and they sound fantastic. Every bit as good as the Euro stuff - they just each have their own flavor.

    In a high gain circuit I think a 70's GE short plate would work best.They tend to have low microphonics and are a warm sounding tube.I have a few labeled Fender special design that sound quite nice.

    I have an Amperex BB in V1 of my Splawn and I like it very much! I also have a Millard 7025 in V1 of my Vox AC15CC and it sounds good there too :)

    I like the long plate Sylvanias with high gain, don't know why but they just pour out the harmonics. For clean, it's tough to beat the RCA's.

    Really depends on the amp.Sylvania short grey plates are one of my favorites for less bright early break up. I call it "the better RFT". RCA short plates for a more "in your face" aggresive high gain sound. GE long grey plates for a more rounded but still present high end.... I just keep rolloing them until I find the right one for the job. Bob

    pretty much all the JAN Phillips I have used over the years have been really microphonic

    I had a few RCA 7025s that sounded spectacular in higher gain applications....

    Yea, I bought 5 and two were/went microphonic real quick on me, they were supposedly NOS, not ANOS, but they sounded very good.

    Jan Philips 12AX7WAs, on average, have about the worst microphonic performance (expecially in high gain amps) of any 12AX7 right out of the box. Doesn't matter if they're new or not.

    I was digging through my old tube box and found two 12ax7's that I found in a old Carvin T-100, I pulled them cause they say Realistic on them, the EL-34's were Realistics too, figured they were radio shack Chinese specials. Well upon closer inspection, the 12ax7's say "Realistic 12ax7 USA" could they really be re-labeled tubes made in the USA?

    Yes, a lot of Radio Shack tubes were made in the US and even Great Britain.

    Yea, I'll shoot them and try and get them up. The Carvin T-100 was old, probably one of the first years of production.

    RCA 7025 and GE's are sweet. The RCA's are the lowest noise and least microphonic I've heard.
