Tube Rolling

Hi Guys, I am going to be tube rolling very soon with my Primaluna Evo 300 Pre-amp &  Primaluna Evo 400 Power amp, Has anyone tried the new Brimar CV4003 / 12AU7 / 6189 for the gain tubes and the TAD KT88’s- STR Redbase for the power tubes ?

Many Thanks

Steve.

You might also want to reach out to Brent Jesse.  He is more than happy to share his experience and opinion on which tubes to use in what equipment to achieve the sound / change you are  pursuing.

I rolled the tubes in my PrimaLuna Integrated. Biggest impact was moving to KT-150’s.  I believe took the sound to the next level.  Also moved to NOS 4003’s and no way as an improvement as the 150’s.  I would start there.
