So i was crusing another forum and came across this a few days ago
and ran into this.
http://diyaudio.com/forums/showthrea...highlight=6ar8
and then decided that for those people that wanted a tube front end
and solid state output then this was the ultimate item as it had all
sorts of things going for it like ultra low inherent distortion without feedback,
the volume control of both channels with a single pot, balanced input
without a transformer, balanced output without a transformer. In short
really sweet. So i bolted a solid state output to it. With a servo of course
because as everyone knows i don't like caps in the signal path. There is
of course one cap in the signal path, but it is in a place where you can
go absolutely nuts with a high quality cap.

All open loop, no feedback. About 100mw into 300 ohms at .03 % thd.
(verfied with berkley spice). No i have not built one yet, i won't even
have the tubes till later this week. These tubes are available and cheap.
The tuberollers might have a problem with this one however.
