User Experiences on Sophia Electric Tubes

Hi Sophia Electric,

I would like to start saying that your tubes are AMAZING! REALLY REALLY THE BEST TUBES EVER MADE. Congratulations.
I replace my old ECC82 (12AU7) and 300B with Sophia’s and my amplifier is INCREDIBLE.
Are you thinking to build ECC81? I put G*nalex, M*llard and others, but none had the amazing sound of Sophia’s.
I really wish that you must need to build ECC81 and 6h30.
Good luck,
