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.

Personally I prefer solid state powering my dedicated home theater.  And for music much prefer the tonality and nuances to an all tube analog front end.  

@yogiboy  I reached out to Mike to verify I can run a lower power tube. Hopefully gear back soon.
Thanks aj523.  I have an ARCAM AVR550 for my home theater and use this also for music.  I have not installed the two rear surround system speakers so all of my sound is coming from the front speakers.  Actually, the sound is really good  I have a pair of Paradym 85F towers, but added a pair of REL S2 SHO subwoofers.  These really helped the sound stage and took some weight off the towers to clear up the mids and highs.  I dialed in the volume of the RELs to 40% so they would not sound too bassy and they seem to blend well.  I would like to have a dedicated two channel system after adding the rear surround speakers, but do not know how to do this from one pair of speakers and subs without having to reconnect the speaker wires each time I want to listen to  2 channel.  I did like the Parasound integrated amp.  The ARCAM AVR850 has the G technology which provides the first 50 watts in pure A quality amplification.  However, this costs $6,000.  Everything in this hobby costs a lot.  I also added a BlueSound Node 2i and the high res and MQA really adds to the quality.  I was talked into adding a ProJect S2 DAC and I preferred the Node 2i played by itself.  The DAC made things sound too thin.  I also notice better sound quality/sound stage when playing MQA.  Might be smoke and mirrors because no one in this group likes MQA.

Thanks again for your response.  Everyone in this group is so helpful and knowledgeable.  Just wish I had more money.
i am not a home theater guy, but if i were, i would agree that HT should be run with solid state gear to deliver the clarity oomph and reliability/low maintenance over long stretches - tube equipment makes a lot less sense here, as to me tubes mainly provide better tonal on acoustic instruments and voices, and also imaging - much more valued in 2 channel music reproduction...
