Tube Rolling

I am using some of Upscale's "Kevin's stash" Gold Lion 12AU7's and they sound great with 0 noise. They have a warmer sound than some of the others. Over the years, I have probably purchased @20 tubes from them. I've had very good experiences buying tubes from them. Same with Brent Jesse. In case you're interested I have a set of 4 reissued Mullard KT88's in my stash that I bought from Upscale and never used. If you end up trying out those Brimar 12AU7's, I'd be interested in your feedback. 

  Veerossi. What power tubes are you using with the Gold Lion 12au7s.  Which Primaluna do you have and would you say the sound is close to a SET or maybe even a 300b amp?

The NOS Brimar CV4003 has a moderate amount of warmth with extension up top and in the bass. Not as warm as Mullard, but is more detailed. I’ve used them in preamp gain stages and also in my amps.

Brent Jesse is a great dealer, but the CV4003s from Upscale are low noise and have lasted for years. Just so there's no confusion with other tubes, these have box-plates.

Great selection of tubes, extremely knowledgeable, and will give an honest opinion.....buy with confidence

Brent Jesse’s site is a fantastic resource of information.  When you want a little info on a tube’s characteristic sound it’s there. He himself has always been helpful to me in finding uncommon tubes that he didn’t even know existed.  
whenever somebody asks me what a certain tube sounds like I tell them to look up his site.
