Mikael Abdellah SE KT88 ideas and questions

I am planning to build stereo version if this schematics: http://www.diyaudio.com/forums/attachment.php?s=&postid=671676&stamp=1119993206

I am planning to make it fixed bias.

Can I use ECC88/6DJ8/6922 instead of 6N1P without any modifications?

Would using the cathode follower give better sound? From my own experiences, feeding from cathode followert hte sound is more compressed but also more focused and punchy instead of feeding from anode.

Thank you.
I just built a stereo (dual mono) version of this amp and am very impressed with the sound.

From what I've read, you can use the ECC88/6DJ8 without any modifications. I've been meaning to try this as soon as I buy an ECC88 tube.

I don't think you can drive the KT88 with a cathode follower, after all a cathode follower only has a gain of around 1. Others will know more about this than me though.

Good luck on your build, I think you will be very happy with this amp.
