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.

I used those tubes from Upscale in my Rogue ST-100, I really liked them and would swap with some Telefunken's, they both gave a nice contrast and kept things interesting. I thought the Brimars had a really nice tone and the telefunkens were a little more dynamic. On the Rogue, I believe these tube were the phase inverters, Rogue told me the phase inverter tubes had the biggest impact on the sound in their amp. For what that's worth.
