Head-ups for fans of AricAudio designs. His new Super 211 SET two chassis amplifier

Many of you who own some of Aric's preamps/amplifiers already know what a talented designer and master builder he is of great tube gear.  I'll be getting in a few days his first two chassis reference 211 based SET amplifier for a review for Six Moons.com.  He went all out in both design and parts quality in this new creation.  Based on my past experiences with his gear, this is something that might be very special, indeed.  My two favorite power tubes in SET amps are 2A3's and 211's. You can also use 845's in this amplifier.

Why do they use SRPP input stage and EL34 driver?

Hi @aricaudio ,

Thank you for reply.
I know that some designers use 300B tube to drive for 211.
300B is even more linear and transparent, but it is much more expensive than EL34, and not everybody like 300B sound signature. EL34 should sound faster.

I never tried SRPP input stage. In my 300B DIY amplifier I use single half of 6SN7.
But I have 6F6 driver in triode mode. And 6F6 is more easy to drive compared to EL34.
I heard 6SN7-6SN7-KT88 SE amplifier and it sounded very slow. One half of 6SN7 is not strong enough to drive KT88.

Regards,
Alex.
