    Default AMPEREX/BLACKBURN MULLARD EL-34'S/6CA7'S.





    Scored a matched quad of NIB/NOS Amperex labeled Mullard Blackburn FX2 EL-34/6CA7's for an super low price. The Holy Grail of EL-34's.
    Guy had bought them many years ago for a JCM-800 but never put them in, amp long gone.

    Every where else wants $500 to $1K+ for a quad if you can even find them.
    2 matched pairs. Should be here by the weekend.

    I'll report back with the results.

    Nice. How do they compare to the EHX 6CA7 I have in my Tweaker 15?
    Epiphone LP Standard PlusTop Pro
    Ibanez SZ320 / A8 DD103 bridge.
    Ibanez RG270 / Screamin' Demon bridge.

    What are you putting them in?
    Right now I'm running a JJ's 6CA7 in my Picovalve. I like it but I am curious to hear how a quad sounds in big amp. Keep us posted.

    Holy tube score, Batman!

    Love new tubes. Makes playing so satisfying.

    I once found a guitar amp in the garbage, a Peavey Studio 110. It caught fire at the first gig I played it at.. But it was at the end of it, thank god.

    So SAYING "freakin amazing tubes" doesn't do these justice. They're like the Thoroughbred Race Horse of EL-34's. Secretariat no less. The Tungsol EL-34B's i been using last 10 years are great tubes but nothing like these. Bias on the Amperex/Mullards isn't as tight tolerance as the Tungsol but the Mullards are in a Galaxy or their own. DEAD QUIET. Almost unheard of for a 54 year old set of power tubes. I can turn up the preamp gain higher with less noise & pedals don't have to work so hard to get really good gain. Midrange out da ying yang. Chimey/shimmer/articulate as a MoFo. If you have an old Marshall or similar there is no substitute. I know most folks cant drop $500 to a Grand on a quad of power tubes but i got this quad for $300 [2 matched pairs] and it only took me 15 years of looking LOL>
    No clips as of yet but take my word .............. MY WORD THESE FUGGIN TUBES ARE GOOD !

    No warm up best i can do ATM as ive been asked by a ton of peeps to get something posted. Cant play at volume due to neighbors.

    Guitar is a Gibson Explorer.

    The percussive attack & articulation is unlike any power tube ive ever had.

    there really is something to be said for old tubes in old circuits. i have a pair of gec kt66 that sound incredible. ive put them in a tweed bassman, 5e7 bandmaster clone, and an old 1987 head. sounded incredible! i dont know if there is as much sonic benefit to using old tubes in modern amps since they were designed around/with modern tubes but i dont play through many of those amps any where near as much so its more of a casual observation than anything else

    How about a tube A/B comparison of Mullards you just bought versus a fresh set of Tungsols, Svetlana, etc etc

    That would be a hot and interesting video

    Bah. Who wants those crusty old tubes? They'll prolly burn up the first time you power them on!

    Agreed, the CP Tungsol EL-34B is a decent tube, ive used them about 10 years but the XF2 MBlackburn Mullards dominate.

    TS video the Master was on 4 with 8db cut on the hotplate. Mullard Master was only 2 with 8db cut and it slays the Tungsol even at a lower volume. The Mullard is only going to get better the more you turn it up.

    I haven't been able to crank it yet due to neighbors but i got that to do !
