    Is there anyway to find out what all the numbers mean after the main model of the tube?

    Like say 6L6GC or 6L6EH?

    I thought they were just like date codes or something but i read something that makes me thing they are something else.

    Ha. The meanings vary unless you know history.

    The EH is Electro Harmonix which means nothing except that they manufactured the 6L6.

    A GC however is a historical design designation. The GC was the last 6L6 design with the only post design being military 7581 types.

    The 6L6EH is a copy of a Russian design and is no RCA 6L6GC black plate although they claim it to be similar.

    What makes them cool is the fact that you dig the way that they sound! Of course, other factors can influence your judgement , such as brand, demand and popularity, price paid and current elitist statistical trends!
    I know I have found myself influenced by similiar mass hysteria.....

    Maybe this isn't the right place to ask, and sorry if it is, but what little I have read in this thread is very informative.

    I've been playing guitar since 1980 (other than the recent five year hiatus I just came off of), and have always been a solid state guy. Having spent the past few months banging the rust off, I decided to buy my first tube amp. I figured instead of buying a tube head for my 4x12, that I would start with an upgrade over the little practice amp I had been using, so I got a used Haze 40. It sounds great, but I have noticed a few issues, being that it's used. I figured I would start with a tube upgrade.

    I've been looking at this kit to get me started. https://www.amazon.com/dp/B00VAK94C...TF8&colid=1GK997VSOPCJ1&coliid=I3QEDG8PJZGGWG

    ...also this one. https://www.amazon.com/dp/B015YJ4P6...TF8&colid=1GK997VSOPCJ1&coliid=I2Y2BJJ9GOU6FA

    ...and this one as well. https://www.amazon.com/dp/B00VH5DYS...TF8&colid=1GK997VSOPCJ1&coliid=I3S34DQ0TH1J1P

    I am just curious, which set you guys would recommend. it feels very strange being a N00B at something when it comes to guitars and amps, but like I said, tube amps are an entirely new ballgame for me

    Thanks to anyone who can help me, and sorry, if this was the wrong place to post this. I just figured this is a subject that gets asked often, and this board might not need another thread asking the same. Cheers!

    One of the best sounding EL34's ever made. I picked up this used pair fully tested with >80% life left in them for my Plexi modded YBA-1.

    Buying tubes is good practice in my opinion, keeps the supply flowing. I stockpile other components as well.

    Greetings to all In regard to Marshall Majors, I recommend Sylvania 12AU7WB for the driver, before the KT88s. Have ran across several Majors with 12AT7s here; not good. This is a low impedance driver stage, and the Sylvania tubes will give a good life here. It's good to be back on the Forum..so far I'm still cancer free
