Nope. They won't. I asked and they 'don't recommend it.' I can understand why, though. They make it as easy on the end-user as possible. But a good tech can always do it. Not too tough of a mod - just replacing a resistor with a pot...
rabies said:stokes said:Mesa wont do it and doesnt recommend it because if you have an adjustable bias,you wouldnt have to buy tubes from them anymore.
I think that's lame as sh!t and one of the reasons I'm moving away from Mesa amps...
camsna said:Well. I don't think it's business strategy. I doubt Mesa makes much profit from dealing tubes! I think it saves headache for them AND most Mesa users. Most guys don't know what tubes are or what they do or that they're any different than light bulbs. And they shouldn't have to get their amp biased every time they swap out their tubes. Also - Mesa doesn't have to worry about biasing issues. They just set the bias range and sell tubes that fall in that range. Plug 'n' play.
But for those with a more discerning ear . . . bias is another thing that we like to monkey with
rabies said:off topic but my thread so what:
I'm reading the manual for the rivera tbr series (out of production).
http://www.rivera.com/manuals_html/tbr-manual.html
very thorough and informative.
there are at least two references to chinese tubes:
Warning: Never ever use Chinese EL-34s, 655Os, or 6L6GCs. They are mechanically unstable and will shorten the life of your amplifier.
never heard that before. so do GT and Mesa not use chinese tubes? only russian then b/c the only other option is JJ's which are slovakian for current production tubes?
