Constant noisy tubes maybe go solid state?

I have a Quicksilver Line Stage Preamp (12AT7) mated to an Odyssey Khartago Stereo. Overall I like it. Way too much gain but I digress. Weeks after receiving it I rolled in a few different tubes, kinda fun to color the sound signature. I liked rhe RXA black plates I got and those stuck around for more than a year. They started going microphonic and making noises so I ordered another pair (noisy) then another different vendor (blasts of white noise) and another set that arrived today (one is noisy as holy hell and one seems fine).

So where does one order preamp quality tunes that are quiet? Is there something I’m not requesting when ordering? Maybe dump
snd go solid state? I’m trying to be humorous because I’m pissed. Ha.

Tubes are funky devices and as soon as they are powered up they start wearing themselves out as mentioned by a well known audio company.
I don't use tubes right now because the new tube stuff sounds too much like good solid state and I sure wouldn't use tubes in a surround sound application.
If you do use tubes the most important thing is who you source them from but I still look forward to buying a tube preamp again for the use in my two channel stereo.
