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.

@jjss49  I’ve heard that about Don. Mike is the same way. If I were to add a tubed power amp it would probably be one of Don’s although Mike’s are also highly regarded.

I have lowered the gain on my phono preamp swapping the 12AX7 with a 12AU7. You might see if you can do the same with the QS line stage!

12AX7 gain of 100
12AT7 gain of 60
12AY7 gain of 45
12AU7 gain of 19
@gochurchgo
Yes! The gain was too much with the cartridge that I use so I swapped to a lower gain tube in the phono preamp!
Churchgent,
I posted my recommended and not recommended brands for
your review. This advice was apparently too specific for this
group as it was removed. Good luck to you. I am done with this
