LOL I have an old early-70's Fender Twin Reverb tube amp with the original electrolytics. It doesn't see regular club action any more (I am older and have smaller/lighter amps for that), so I turn it on every few months and warm it up, just to rebuild the dielectric in the caps. Otherwise it may get exciting the -next- time...

I've read you can revive old tube equipment that has set a long time with a variable transformer. To slowly raise the voltage so the caps don't blow.
