Hi friends!
I need some help please. I own a triaxis with 2:90 poweramp. Last night, i was playing with my band and my amp's volume raised incredibly. I checked the output meter in my multifx and it was normal, so i asume the problem is in the poweramp. I called mesa's support and they told me to check the power tubes, he said i can change them by myself. Then i called my local musicstore and asked them about retubing and they said i should take the amp so they would change the tubes and ADJUST THE BIAS. I think there is too much misinformation for a newb like me....
1.- Has anyone experienced volume rise with this amp? I've only heard tube failure causes volume drops. Volume rise is new to me.
2.- I run my amp only trough channel A. Are the tubes in channel B wearing as much as in channel A? If not, should i just replace the tubes from channel A? Will i damage my amp if i use one channel while the tubes in the other channel are failing?
3.- If i buy 6L6s from mesa, do i need bias adjustment? can i change them by myself?
4.- Does the color in 6L6s matter so much? will i damage my amp if i use wrong colors?
5.- What are the 3 tubes inside the 2:90 for? should i change them too?
6.- How often do you change your tubes?
Thanks.
