Replacing the shock mounts should no effect alignment, neither will replacing the power cord, replacing the dial scale (though it can be mechanically out of alignment it's not the same thing) or removing the knobs. Depending on what tube is changed it may or may not effect the alignment, like changing the 6A7 could.
