Preventing TV Damage

[vintagecollect]

What does everyone use for surge control for all of their own old TVs. Open to suggestions. Wouldn't this prevent undue wear not only to caps, but to all tubes- including CRT?? Do modern surge protectors power strips just regulate surge current when the set is first turned on??? I'm going to use a variac whenever turning my older sets on as a precaution. Gradually adjusting voltage to 100% over several minutes. I know people use these to wake up TVs after a long hibernation------, good idea to use all the time????
