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 check my own. I buy in lots and bulk, have for 40 + years. The folks here will chime in on Vendors that will check and MATCH your valves.
DON'T pay a lot of money, but don't cheap out.. 12AT7s there is a slough of those around at good prices..and quality matched valves..12AX7s you can spend a few quid, more than 12AT7.

BUT if the shine has wore off... go SS it is easier in the long run... Me I've always used Valves, kind of second nature... I had to be pushed into SS.
Its great stuff, though...

What do you mean? It quit working, or the noise went away?

All these problems with valves... It almost sounds like your system is right in front of the house main. Some crazy field expanding and contracting, "like breathing".. You ever consider that? Am I crazy for thinking that? Does location change the problem with the unit?
Have you yo,yo ed the unit. Pick it up and set it down, while playing. I know you have to be very careful.

BUT at one point I’d just about try anything.. LOL I’ve found some weird stuff, BY doing weird stuff.. Get creative!!!!My good man...:-)
