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.

I can't believe no one has chided you yet for turning on all all your gear while the power amp is still on! I have the Khartago running with a tube preamp and yes I keep it on 24/7 like Klaus recommends  however you definitely should switch it off to boot up the rest of your system and then switch it on again quick. Don't turn it on until at least 15-20 seconds after turning on preamp. 
From what I've read and been told you absolutely do not want that horrible distortion pop running through your system upon boot up. I dont think its causing your issues but its certainly horrible for your system. 
The rule is always amp on last , amp off first.
