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 like taking care of a small child, they give you wonderful moments but need a lot of care.
If you want the best SQ, IME, it is still going to come from tube gear, unless you spend the very big $$ and go for top ss. OTOH, if you want greater reliability of the sound and no fuss, and SQ is secondary, then ss is the way to go. BTW, Brent Jessee offers a two year warranty on his tubes, something that I took advantage of when I bought from him, I highly recommend it. 
Many of these tubes are what are considered 'pulls'. IOW, they are tubes that have been used for years in some piece of gear and have been removed to now be sold as NOS tubes. Nothing wrong with this IMO, so long as the tube is tested and correctly disclosed as a) used and b) tested to be sure it works to spec.
I currently have some Telefunkens that are labeled as Dynaco and have obviously been 'pulled' from a Dynaco kit. They sound great, are made by Telefunken in Germany and are perfectly good as to test etc.
@cleeds I agree with this 100%.
Interestingly, in the tube re-seller world, there seems to be a propensity to label tubes as NOS. These very tubes are in fact used and measure as if new. I guess if one questions how many tubes from the 1950’s -1970’s have survived brand new in a box (that have NEVER been inserted into a tube socket), the answer to what is going on becomes more clear. Not saying i totally agree with the practice, but how many times has one bought a NOS tube and looked at the pins to see that they are brand new....I know I have bought these from so-called ’reputable’ tube re-sellers and the tube pins are anything but brand new! I was disclosed that they come in an original box ( mostly) and they test as new. ( which is also a ’relative’ term).
