I am unimpressed by the quality of currently available electrolytics for tube-era voltages. They seem to be made to last the length of the warranty.

When I replace electrolytics, I use the good 105 degree C Nichicon and Panasonic caps, and exceed the origional voltage ratings by wide margins. I usually double a 25v rated 'lytic with a 50v, and for 250v I always use 450v, etc.
I like overbuilding these TVs when I restore them. The last thing I want to do is open them up again when I'm finished tweaking them.
