Biasing for a dual rec

[mesanomad100]

Good day folks,I was always under the impression that with a dual rec(most mesa's)the bias select switch on the back allowed you to select betwwen diffewrent types of tubes,for example 6l6's and el34's,does this mean that you can use any company's tubes in the desired setting for example jj's 6l6's in the 6l6 position...or does the amp need to be rebiased and all that,surely they tubes with still be drawing the same amount of bias if they are 6l6's or does this only work if they are MESA tubes which results in the amp working fine with their tubes only

the reason for asking is a post left on another thread I posted called
Eurotubes,just got me worrying thats all I dont want to have my amp rebiased an all that,I just dont want to use mesa tubes I want a set of JJ's in that sucker

cheers guys
