    Hi,
    I have an old Mesa Boogie Studio 22 combo that needs new preamp tubes.
    Which brand would you suggest? Any suggestion will be more than welcome.
    Thank you very much!

    I have the same amp, awesome, isn't it?!?!

    I don't remember what I put in there, I think I have some NOS ones..... I rarely play it anymore. I'll check tonight.

    I am interested in other people's choices.

    Yes, it's a cool amp. I have the one with the "wood" cab, very good looking. I guess some NOS would be the best choice, but I think I would like to keep it simple and go with some new production ones.

    of the new production 12AX7s I've been most impressed with the Tung Sols and the JJ ECC83s.

    JJ's are always good. Otherwise if you can spend the dough the new GT12ax7M's (mullard copy) are phenominal.

    At one time, a high percentage of reissue Mullard 12AX7s were prone to microphonics - I don't know if they have improved - make sure your tube supplier has culled out the bad ones.

    Yes Tung Sol Reissues are the best I've seen in new production, and I've seen them all.

    OR, spend 2.5X as much on a NOS Tesla E83CC and get better tone and 5X longer life. Do the math:)

    Nobody's mentioned Elctro-Harmonix 12ax7EH. I can only compare to JJs, but EH has more top end shimmer and a tad cleaner/less gain tone. I have EH in v1 and JJ in other spots on my Laney. Very good combo.

    Tung Sols for current production. Mullards for NOS. The Mullard is a great V1 tube in most any amp and you can get a good one off EBay for $35-$50 or so.

    Or maybe a bad one, or maybe a Chinese tube with a Mullard label and/or box, or....

    I've bought quite a few tubes off fleabay and I've only gotten one bad one. I've bought far fewer tubes from dealers and have gotten three bad ones. One was excessively noisy and the other two blew up. Oh, I just read your signature. Two of those tubes came from you. hmmm....

    Depends. I assume your talking long plate. The less desireable short plates are reletively cheap-also far less nice IMO.

    I'm assuming you're joking about the last part since I have less than 1% problems in the field and I honor all warranty exchanges.

    Mike ....

    you make excellent points ... all of them!

    I need to take a picture in my office one day of all the junk I have in here that was described as something other than what it turned out to be.

    It seems every week there is a new tube dealer born from somebody that found 500 misc tubes for $25 on ebay.

    I wish I was joking. You did exchange the Brimar but the Mullard shattered into a thousand pieces when I tried to remove it from the amp. had to toss it. The only thing I could have sent back was the box. Didn't think you would go for that so I ate it. :(
