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.

Just take the equipment out in the driveway, put it up on cinder blocks, connect to the oldest and funkiest speakers you have, wear safety glasses, and have a non-liquid CO2 fire extinguisher ready to hand. No worries...

If you wait until the 4th of July to do this, you get extra credit for any sparks which may be produced during the process.

For a bit of a preview, go to YouTube and run a search for *4000W Tesla coil test" or "Vanguard (Flopnik)."
