Constant noisy tubes maybe go solid state?

The problem with your Rogue is most likely not the tubes but just a higher noise floor with the component. Could be an issue with gain and also probably just the price you pay for a less expensive component. You can only do so much for a given retail price and certain short cuts are often taken by manufacturers in order to reach a target price.

It’s fine. Things are running and I’ll be moving on the QS next year anyway.

Hmm. I did notice QS changed their contact page some. No more fill-in page. Shows email address only. He did respond back quickly though.

re: old tubes - I do know people try different quality grade tubes in his preamps and the stock JJs he provides work well 99% of the time, functionally. Sure, others sound better and yet some old tubes from eBay and others with no reputable curve tracer or proven reputation and good results are a crapshoot. Can’t fake it on old tubes, as we all know too well. Best to buy from reputable tube resellers with real guarantees.

A friend had issues with his QS preamp as soon as he started "saving money", "getting a better deal" buying sh*t tubes off eBay. He's got good tubes now, all quiet again on the western front with his QS preamplifier. 

Selling it? If you decide to put that QS preamp up for sale, be sure to post it on Agon, someone here will grab it and make good use of it! Best of luck.

Just chatted with Mike Sanders at QS again over email a few times.  He wanted to re-share he "responds to all emails" and suggested people may not be using the correct email address if they are not seeing a response.  

Note:  I checked and see his current gmail address via the "contact" page on his website is NOT the same as the old one some of us may have had last yer.   See contact on his site for the correct one to use.  

I have used 12AU7 tubes in that Quicksilver to lower the gain! You should do a little research on your gear before making a purchase. There is nothing wrong with that QS preamp. You mismatched the amp and preamp!

@donvito I researched the hell out of it. You should read a thread before commenting in it. Go ahead and search. Let me know what you come up with: TLDR zero.

never said anything was wrong with it and in the original post I noted that I realized about the gain.
