Is tube "thunder" power related?

Hi.
I bought a new phono stage recently. It's a tube model (WPP100C). One of the tubes started "a severe wind noise" in one channel...I switched the tubes and, sure enough, it switched channels... bad tube. But now the other tube is starting to "rush"..
I live in an old house, with suspect power (downtown San Francisco...lots of surges).. I use a power strip, but the ground isn't reliable. Can power fluctuations ruin a good tube quickly??? I've had this phono stage for only a few weeks..

Thanks for any input.
