sick thread on LS bias mod with apparent good results: http://forum.grailtone.com/viewtopic.php?f=31&t=45632
would the Mark V benefit from a bias mod as well?
I thought I saw some Weber bias rite readings on here for a V and it was reading a little hotter than a IV or III.
I don't need 70% MPD, but 30-40% MPD seems wrong to me (unless you're really interested in lengthening your power tube lives...)
I really wish Mesa would offer this as an option on their amps, it seems like all the boutique amp makers (e.g. Diezel and Rivera) allow for adjustable bias such that you can plug in different families of power tubes. It's almost like Mesa doesn't believe their tubes and/or components (e.g. OT) are tough enough to handle "normal" bias setting in excess of 50 or 60 % MPD...
