@invalid I wish Mike from Quicksilver would have replied to me. I’d be really curious to know if I could swap in 12AU7 or AY7 to lower the gain. I’d have some in the mail already.
oh well.
oh well.
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.

You won’t hurt the preamp, by trying a 9 pin, 12 Volt, with lower gain.
ie:https://amptubes.com.au/my-amp-uses#:~:text=You%20can%20interchange%20a%2012AX7,gain%20and%20others%.... You're still going to want the lowest noise tubes possible, obviously. The major misalignment, in my opinion, seems your power amp/speaker combo. |
@rodman99999 you are correct. The speakers I ended up with were not what I was originally aiming for. So yes the high gain amp and high sensitivity speakers are a mismatch. Add in high gain preamp and here we are. But that said I’m very happy with the sound. I’ve had people over who came to hear “a car wreck of a system” and were impressed by it. It shouldn’t sound as good as it does for what it is but yet it does. Originally, 4 years ago when I started I was looking at Odyssey Liquids, used Pulsars and Cantons. I heard Heresy IV’s on an all Pass slabs system and that was it. |
@noromance I swear I read they may not be interchangeable due to plate voltages and heaters and what not. I’ll definitely roll in some AU7’s and SY7’s then. See where I end up. @yogiboy I saw a post of you saying how good the WS phono is and I remember thinking “why 47db for mm?” I guess if I can drop down the gain via tubes I should reconsider it. |
