After starting up well over 200 pieces of tube gear, I have never experienced a high voltage capacitor failure to date. For the most part, I eventually replace the B+, bias and all coupling caps if I keep the equipment.

...10% failure of electro's at first start up.
and 10% more that make it for a while before giving up the ghost.I would guess these numbers includes 20-25 int. amps, 30 or so monoblocs and stereo blocs, a 15-18 tuners, preamps, and 4 recievers.
Like you, if I keep it, it gets fresh caps (with some exceptions where cap is very overrated as in some pro gear).
Take care,
