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.

Like a few others not a fan of the sound of JJ tubes. Been pleased with tubes from Brent Jessee.

You can go solid state.  Then you would be moving from constantly noisy tubes that can easily be replaced with quieter tubes or you can go with constantly noisy solid state devices that can't easily be replaced.

I’m sending one tube back to him. He will make it right no doubt.  The nice thing about the Philips is that it rolls a little top
end off so there’s less hiss hahaha (my speakers are 99db). I do like the aphillips but the RCA are still my faves. I’m looking into others mentioned in this thread as well.

Very few JAN (military) tubes were electronically any different than the normal tubes in the same family. They will sound the same, last the same length of time and, at best, were specially tested for certain characteristics like shock/vibration.
