    Excellent tubes... Right up there with any of the NOS cork sniffer varieties. They were stock in Marshalls from late '70s until mid '80s. They were also the Groove Tube 7025 for many years.

    I agree with Swarty and the nice thing about not being Mullard or Telefunken Smooth plates is that they can still be had for a more decent price if you can find them.

    Tungsram was one of Telefunkens subcontracted manufacturers.

    From what ive learned is that These usually have a break in time of about 48hrs.

    Supposedley go real well with fender type/ marshall too.

    Those are fantastic tubes for clarity and definition. In my opinion, they outclass Telefunken smooth-plate ECC83, as they're less compressed and have a tighter bass response. They won't break up as easily as some (such as the RFT ECC83, if you're familiar with it).

    Looks like they're from the Zeitmann crew. Those are great guys. I've gotten some mighty tasty Tungsram EL84 from them.

    You are correct sir , they are! Thanks for the response. , I am familiar with the high gain of the rft(have a few). This might tame down my gain monster laney. Probably wont use them all together, ya know?

    Cool , cool. I feel much better about my imulse buy. :dude

    The Tungsrams will clean up the overdrive a bit. That was a fine impulse act. Perhaps the beer angels were guiding your hand?

    I like to mix preamp tube types, depending on what character I'd like and what the circuit is doing (and sometimes, which guitar I'm using). I've got five different tubes in the five slots of my Triaxis.

    For the Triaxis, the "V1" is only the input tube in the Lead 1 mode - I use a Raytheon black-plate/halo-getter 12AX7A there, for its uncompressed twangy cleans that breakup into sweet crunchy overtones.

    Triaxis V2 is the main input for all other modes (and the gain tube for Lead 1). I use Mullard CV4024/12AT7WA ('80s version) there because of its solid lows, and open/airy transparency. I also like lowering the gain of the Triaxis so I can control the transition into breakup with my playing.

    The Triaxis doesn't have a PI, but I use Mullard CV4024 as well for my Boogie 20/20 power amp. I also like Raytheon 12BH7 for the PI in the 20/20.

    Great tubes! Very similar in tone to RCA 12AX7As.

    You are correct sir.. They are a cross between an RCA and an RFT to my ears... It's funny but I originally heard of Tungsram tubes in the late 80's early 90's when I got my Symour Duncan Convertible 100 amp. He recommended them in the manual but told people they could get other tubes with lesser results basically! HE was on the money.. I have a bunch of Tungsrams and they're great for clean , blues, or hi-gain
