Members Eye_Of_The_Liger Posted April 6, 2006 Members Share Posted April 6, 2006 If I buy a matched set of power tubes to replace the tubes in my amp, and if they're the same tube type, do I have to rebias? Link to comment Share on other sites More sharing options...
Members the russ Posted April 6, 2006 Members Share Posted April 6, 2006 same tube type like they're both 6L6's? yeah, rebias. or same tube type like they're both 5's on GT's hardness scale? then no. Link to comment Share on other sites More sharing options...

Members trichrome Posted April 6, 2006 Members Share Posted April 6, 2006 it depends what kind of amp you have. mesa's are pre biased for you, i don't think you have to mess around with it on a mesa. Link to comment Share on other sites More sharing options...
Members tommythelurker Posted April 6, 2006 Members Share Posted April 6, 2006 "matched pair" only means that those two tubes match each other, it doesn't have anything to do with your need to adjust the bias. Those two tubes, while matched to each other, could be completely different than the tubes you have in there now and need a completely different bias setting.

But you must buy mesa tubes in that case (or another vendors that specifically screened them to work in mesa's). Don't just put any old tubes in there.

Members Eye_Of_The_Liger Posted April 6, 2006 Author Members Share Posted April 6, 2006 So if I have to rebias, how can I tell the voltage that the tube is operating under? Link to comment Share on other sites More sharing options...

If you're "too lazy" to read that, you probably shouldn't be biasing your amp yourself (unless you already know all that, but then you probably wouldn't be asking vague questions like "how to measure the voltage"). Take it to a tech or get the bias rite with the VI option. http://www.webervst.com/bias.html Link to comment Share on other sites More sharing options...
