Tubes Asylum

Questions about tubes and gear that glows. FAQ

How steady should my bias measurements be? I set them to 1.56 about 3 weeks ago and last night i checked and it had drifted to 1.59 on both sides..i assume this is ok, yes? I have used it daily for the 3 weeks.
The Dyna is bone stock with (what i think) are Mullard EL-34's.
And another question, is it wise to lower the bias (to 1.25ish)so as to prolong the like of the tubes, NOS Mullards would cost more than I paid for the thing!!!!
Thanks in advance.
