You can go solid state. Then you would be moving from constantly noisy tubes that can easily be replaced with quieter tubes or you can go with constantly noisy solid state devices that can't easily be replaced.
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.

@gochurchgo first of all, glad you have quiet tubes in the unit working now... that’s good second, brent is a good guy, good vendor, bends over backwards to get it right... bear in mind tubes get shipped in little boxes that usps etc love to throw around like nerf footballs... i seriously doubt brent would send a noisy tube on purpose if the customer was buying quiet ones... viva guys are ok, they are commodity vendors (with decent prices) - they get stuff from tube factory xx and yy and they fill a customer order - but they don’t do extra value-added testing in house - like upscale, brent, andy and jim do in their shops as far as i am aware |
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. |
@jjss49 the Phillips in there now are completely quiet. I would add the QS and the Odyssey Candela tube preamp have nearly identical specs according to the website. @yogiboy and testimonials from others persuaded me to go QS over Odyssey. The gain is very hot and I did ask Mike if it could be knocked down and he said his design is not to be messed with. I didn’t press it further. While I like the QS pre, the Sachs SP14 has adjustable gain and asks for input of the amp it will be mated to so I fee like if I go that route at 2x the money then it should match better. I tried attenuators but feel like they quell dynamics a touch (could be placebo). I have a Schiit Sys and pondered putting it between the QS and Odyssey to pull the gain down. The RCA’s front Brent a year or so ago were also perfect and run daily since then. The Brimars (Tubemonger) we’re noisy out of the gate. I may put them back in after reading that sometimes 100 hours can remedy noise. The replacement RCA. From Viva were awful from the start. The newest RCA from Brent has 1 tube that’s fine and the other sounds like a 1000ft wave is going to crash through the wall and sweep me out to sea. It drowns out the music. Maybe bad luck? Brent has been very good, Viva took theirs back no questions asked and like I said before, I’ll never do business with Tubemonger again. I sent Brent a video clip (was trying to upload to paste a link here but I guess they are having issues). I often criticize people who gripe about the Care and effort that vinyl requires so now I’m wondering if I’m not cut out for tube gear. Especially as I’m looking to order a PH16 (Don Sachs) to replace my Lounge phono. |
@tvad That said, I have tried most of the available new production tubes from JJ, Shuguang, etc, as well as dozens and dozens of premium vintage NOS tubes. i agree with the above 100% -- jj's are just downright poor in sound i believe the op has either: a) a sensitivity mismatch between the QS pre and Odyssey amp (as I said earlier, the Odyssey’s are very sensitive, too sensitive) b) a malfunctioning QS pre c) noisier than normal tubes this also reminds use why there is a longstanding market for really good solid state preamps like ayre, pass etc etc |
@jperry Brent Jesse, VivaTubes and Tubemonger. The first tubes I rolled in were front Brent Jesse, the now dead set of RCA’s and a set of Phillips 7062 which is all I have that don’t make me want to commit murder. Viva took their tubes back and tubemonger blamed it on me so they can sit and spin. brent is helping me now but this is so maddening. I get like 3 hours on Saturday to relax and spin a few records and this is where I’m at. |

I have that same preamp. I like vintage Ge 12ax7WA/6201 tubes. You should be able to get a matched pair from any reputable seller on ebay for less than 50 bucks! The GE JG-12AT7WA vintage tube is a rugged, American-made workhorse produced for the U.S. military and used for computers and targeting equipment. This tube is usually very low in microphonics due to its rugged construction. The GE JG-12AT7WA had to work well under arduous conditions and was made with solid support rods and short, gray plates. |
Q) "So where does one order preamp quality tunes that are quiet? Is there something I’m not requesting when ordering?" A) Some tube mongers test their wares for noise (some don’t) and- typically, you must request the best, of those that do. At Upscale; they’re graded. Ask for their, "Platinum" or, "Kevins’ Stash" rated, for the quietest. ie: https://upscaleaudio.com/pages/test-equipment and: https://upscaleaudio.com/pages/grading-matching Brent Jessee Recording is another excellent source, for noise-tested valves. His method is outlined, on this page (second vid): http://www.audiotubes.com/12ax7.htm

After many years (20+) trying different tubes my go-to now is JJ from tubestore.com Not because they are the absolute best - although they are better than most I've tried that's just me in my Melody. But I have never had a problem with any JJ tube. Maybe I'm just getting old or jaded or something but with so many other things out there that can make a much bigger difference with nowhere near the risk of headaches of tube rolling I go with the tried and true JJ. BUT, if I really did want to try something different the man I would call is Dave Thompson at Raven Audio. https://www.ravenaudio.com/ |
Kevin will sort you out. Call rather than ordering and explain your situation. I haven’t ruled out that there could be some other factor at play. I've boxes of tubes that were once enjoyed and ultimately replaced for better and better ones. Most were quiet but you get the odd noisy one. But that's part of the fun. |
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... Regards |
