    Hate to post a redundant thread so first I did a search and found about a bazillion other posts.

    I apologize if this topic has been covered. I've always used Groove Tubes but have noticed a lack in quality lately and it is time for a retube and bias.

    It's for a 50 Watt KT66 so it would be one matched pair. I have had crappy luck in the past so I figured others would have more insight.

    I was planning on a pair of Genelex Gold Lion but if JJ's are any good then I'll try them first but would like some objective opinions instead of sales hype, or maybe there is some other brand that people like.

    ...thoughts, feelings?

    I guess I should add:


    With this setup I have never had a problem getting a good throaty sound with very rich harmonics and good separation between each note when playing chords while only needing to switch the pickup selector and a slight boost for good violin lead tone, not to mention the exceptional headroom on the clean channel, so I don't want to change it but get more consistent than with my current set of Groove tubes.

    the gold lions are another impersonation by the new sensor company, like tungsol... i'm not saying they're bad, in fact i haven't tried them or even heard them, but the fact is they're way overpriced, and the extra bucks you'll have pay for them, is IMHO only because it wares the name of a legend
    if i'm right, steelhorse has put JJ KT66's in his VM, and he's raving about them

    before my JJ KT77's i had groove tubes E34Ls in my DSL... and as far as i know; made by JJ... i liked the GT's, but they are not fabricating tubes, they just restamp them, stating they have high quality standards... and so you have to pay more

    new sensor impersonates a lot of brands, with a price tag, like they're fully replicating the NOS originals... oh well, everybody wants to make a living, right?

    I guess I had got bitten by the hype once again so I'll save the $$ and go w/ JJ.

    It looks like th JJ's will also be smoother. I'll just have to attenuate the "ballsy" knob on my eq.

    Thanks guys.

    i compared some prices over here in europe...
    the KT77's from Genalex are twice as expensive as the JJ's. :shock:
    as said earlier, i honestly never heard the genalex, but i cannot simply believe, they are worth the double pricetag...

    the KT66's are strangely enough priced pretty the same, between brands???????:wtf:
    the JJ is a bit cheaper, but not as different as with the KT77's

    Maybe it has something to do with the way they manufacture. I can imagine those machines are expensive but I honestly have never researched it.

    Or probably marketing. I wonder what the supply and demand ratio is between 66's and 77's or even 88's.

    well, we can fairly say the JJ KT77's are very popular...
    so if these sell good, they can produce them in large numbers, which make them less costly to produce

    I love JJ's. I had GT6L6's in my Dual Recto but changed all the tubes pre's, rectifier and power to JJ's. GZ34's in the rectumfire :))) KT88 and KT66 power, and high gain ECC83 pre amp tubes.

    Massive difference, totally different amp and every mode and channel is amazingly better.

    I want to add though that the GT's weren't bad, the integrated quad is just better imo.

    Not me, but I had seen that page and one of my buddies said he was in the process of acquiring them. I'll try to find out what he thinks.

    He really should join this forum, he could learn a lot.

    Contact them and ask them for a recommendation. They're really good about getting back.

    The Winged C's are good tubes too imo.

    those tubes come stock with every marshall, along with shuguangs in the preamp
    they may be pretty good, but i prefer the JJ's...
    the GT-E34Ls was an improvement in the DSL IMO (those type's are JJ's by the way) the KT77's were a step further, to what i was looking for

    tried them in my new JVM, and they were a winner too instead of the winged C's.... but of course, that's another opinion :)
