I wouldn't go changing tubes unless what you have test poorly.
A guy in my old audio club knew his way around tube amps, preamps, etc, and did a lot of bench work. I remember him telling me that undertaking the alignment of the Dynaco FM3 was not for the faint of heart, despite the DIY instructions.
I have the James Lin "Improving Dyna's FM-3" article from a January 1991 Glass Audio I can send you if you're interested. Email me via the Asylum if you'd like a copy.
