    Love me some Brimar! As some of you already know :wink:

    I just looked at your rankings and damn! Those are some killer tubes, and the Brimar, are up there with some of the best ever. Very Cool!

    I also just scored, a backup Mullard ECC82 57' Blackburn! :o2smile:

    OK, I'll play along................. "Let's find the RIGHT Brimars!!!"

    I see lot of versions and military CV designations of the ECC82 / 12AU7's. Is it the vintage (1950's or 60's), the getter shape (also related to vintage) and or plate length / construction the key or ALL of these elements?

    I had to buy 3 pair of those Brimar 12AU7 square getters to get a good pair. Brent Jessee crap pair and another crap pair went back to UK for terrible testing and noise.

    oh, ok, thanks for toning that down. The Melvins sound good with tubes on the Lyr 2!
    Without the Melvins, there would be no Nirvana, no Soundgarden, no Mudhoney, no Pearl Jam, no Alice and Chains, yada yada yada

    I agree about the tolerances. The industrial/military tubes are presumed to be better sounding based on tighter specs.
    I haven't listened to the 491, but I just listened to the Amp 7308s and USN-CEP 6922s this AM in some A-B testing. Clear differences b/w the two.

    Thanks for confirming! The Amperex 7308, is a killer tube, for sure!

    So, IYO, is it the square getter (also denoting earlier vintage) that's the secret sauce to the great Brimars? I understand poor testing and noisey tubes. That just goes with tube hunting and buying. :head_bandage:
    Just figuring out what version is the Brimar King!!!:thinking:

    I have a 60's O getter Brimar cv4003, that I have heard, and will be trying the 56' Brimar ECC82 square getter soon, and will report back. However, the older square getters, always seem to have more magic.

    The O getter Brimar, does sound killer!

    I think the king Brimar, is a square getter 6067, if you can find one. :astonished:

    You have not tried the Brimar yet? The warranty expires in 5 minutes, I'd try them within the warranty time frame.

    Go for mid 50's square getter with a 571 code.

    I know this is not exactly the comparison you were asking about, however I have the Brimar CV491 long plate square getter and really enjoy them however IMHO the ECC82 Blackburn long plate square getter sounds better.

    I believe the military designation tubes do sound a “little” better (supposedly with tighter tolerances)
    Not exactly a fair comparison but my GEC CV6091/A2900 1964 Black Plates D Getter 3x mica. Sound better to me than my GEC A2900 2x mica.

    +1 for Brimar CV4033. Check TubeMonger for 60's vintage NOS. It currently spends more time in my VH2 than Mullard CV4003 or any other tube for that matter -- even my TF 12AU7As and CIFTE 12AU7WAHs. :wink:
