Hmmm. 99% of the time I just plug things in and see what happens. That's what
they were designed to do. If something pops I fix it from there. If a fuse
keeps blowing I use the light bulb in series trick.
On older tube gear I do "softly" bring it up with the variable autotransformer
(Variac, Powerstat), but that's only really because of the capacitors.
Just my 2 cents. I do fix a lot of stuff, though, and don't like to waste time
futzing when I don't have to. Weak parts get replaced. If they were likely to
fail enough to do so when I just plug something in, they need replacing anyway.
