Firing up old tube amps. Should I worry?

Hey, I'm going to fire up a pair of World Audio Design KEL80 monoblocks I built probably 15 years ago. They probably haven't been on in 10+ years. Anything I should worry about? All parts used back then were new and good ones - may have upgraded the capacitors. I don't have a Variac, so I can't ramp up the voltage. They worked back then, but I'm just a little concerned they'll arc or something and blow my speakers.

Find a repair shop with a variac or buy an inexpensive one. There is a good chance you will need it again in the future.

99% it's safe to turn them on.
I believe that this amp has good quality old school parts and despite it's better off recapped it should work.
Don't be paranoid.
