Talked to Mesa the other day.

  1. Had a talk with Mesa Hollywood the other day about tubes and was told I could use any color code of their tubes and it would work,(as long as they were the same color). So has amyone have any thoughts or any experience on this?
    My 400+ has the green code and was thinking of going up one grade to the blue code for a little warmer sound or should I go for the max(red).

    I think you should have adjustable bias controls installed, then you can use the same set of tubes until they blow just by having them rebiased every year or so. Mesa's fixed bias and "grading" system is just a way to get people to buy Mesa tubes way more often than they need to.

    How much does this surgery cost?

    Got no clue, quite honestly, but I guarantee it's way cheaper than buying 12 6L6's every year.

    It's about a hundred bucks, plus a set of tubes if you need it.

    Ish. That's what my shop quoted me - 1.5-2.5 hours of bench time (so 100-150 or some odd)>

    My tech has instaled adjustable bias in serveral Mesa's including my 400+ pictured below. He's a friend so he usually doesn't charge me much but I got the felling it would only take a component tech an hours bench time and the parts were only like $20. If your amps due for a general checkup/servicing too, probably figure in another hours labor for that.

    (Its the little board with the 2 blue trim pots/4 resisters located near the center of this pic, he mounted it with a pre existing screw hole so its a fully reversible mod if ever desired)

    But I don't know why you'd need to change your 6L6's every year.

    That's the general rule of thumb on all tube amps...change tubes once a year.

    Indeed. :rolleyes:


    Imo, the amp's sound comes back to life when you put new tubes in it. Takes between a year or two for the tubes to start sounding like crap.

    Gone to a better place
    Over 30 years for 2 of mine, still going strong. Anyone who wants to send me their "junk" 1 year old tubes, I'll gladly pay shipping.
     
  12. Im sure these are gone. Some of the welding on the plates have bowed and blows fuses at random. Plus I did some research and the tubes are the STR 430's which Mesa says they havent used since 05 and the date of the amp was in 03 according to Mesa.

    Sadley, Ive stopped using the 400+ and using my STV Pro III(still sounding great after 10 years) till I can replace tubes.
     
  13. EUROTUBES boys & girls!

    I used them on my Mesa 400+ & 400 when I owned them. The difference is unbelievable....Mesa wants you to buy their overpriced tubes. Most of the tubes come from the same place anyhow....you're paying for the Mesa stamp.

    Anyhow, here's a shout out for Bob Pletka @ Eurotubes

    www.eurotubes.com

    Your Mesa will never sound any better than with Bob's tubes. Highly recommend them.

    At which point you have them rebiased and they sound great again until the next time they need rebiased. And I'll take anyone's 1 year old tubes too, and I'll pay shipping + $1 ;)

    I've had amps with 10-20 year old tubes in them, fully functional, and then I had them retubed and everything sounded amazingly better. I guess my personal experience is different from some others...:cool:

    Yeah, but fully functional doesn't mean your previous tubes were good. I've had tubes that work in the amp but test bad so it's very possible you had a couple bad ones along the way. The point is that there's no blanket statements you can make about tubes. Replacing old tubes just because they're old isn't always going to make a change in the tone for the better. It did in your case, but it may not in other cases.

    ?!?!

    What? That's crazy talk! There's absolutely no reason to swap out your tubes every year! Where did you learn this sage advice?

    You are being facetious, right?
