    I was just about to swap the preamp tubes out in my SV20H and noticed one of the replacements was labeled E83CC, what I read about it is its a higher quality ECC83 and is a different tube but still a 12AX7. So my question is should I put it in V1 or V3, and what are the reasons why?

    ECC83 & 12AX7 are synonymous...

    One is US designation & the other is EU...

    Before Tesla shut down, they also made a tube called E83CC, and it was a vastly superior tube compared to the JJ version. Both are interchangeable with any ECC83 or 12AX7.

    they say that it's less noisy/microphonic.

    Probably why Marshall use it in V1...

    An E34L is a different design from EL34.
    It has slightly different construction, quality and sound.
    I like E34L better for the most part when it comes to more current production.
    Still it is best to try a set and remember every set can have variations even from the same manufacturer. That is why we test and match them.

    The same goes for ECC83 and E83CC.

    It is best to roll them preamp tubes to see which combination sounds best in your amplifier.

    But they are great to put into an amp before you sell it.

    lol ......

    E34l/Ee34LL/6L6L/Ec803/cc83E all marketing man.
    They even do a "telefunkin" thats just a crappy jj.
    Again all marketing.
    Gotta be smarter than the tube.

    Right now I got the E83CC in V3 and its fine, too lazy to roll tubes LOL, took me over a year to get around to it! But any way, I put a set of Ruby EL34 and PM 12AX7 all Chinese tubes I took out of an Orange amp before I sold it (put JJ's in their place LOL) so now theyre in my SV20H. These tubes got rid of that dark frequency I dont like about JJ tubes, so it made a difference, one other thing these Chinese tubes seem to have lowered the gain a little but no big deal I have pedals to get gain. :yesway:

    I did a sound comparison with the "JJ" Telefunken EL34 which are supposed to be built to Telefunken spec not just a relabeled JJ, and it sounded very much like a Winged C EL34. But then so did the Shuguang EL34 sound like the Telefunken and Winged C for a fraction of the cost, I will never spend the premium on those tubes I'll just stick to Shuguang if I ever buy power tubes again. :yesway:

    I'm just saying I tested them and there is a difference, I dont own them though.

    I like JJs. They're simply perfect for when I need to sell an amp in working condition
