[Boatanchors] HeadWize - Project A Zero-Feedback SRPP-Input Headphone Amplifier by Simon Busb

[William L Howard]

I recently ran across an article on a headphone amplifier at this url

 http://www.headwize.com/projects/showfile.php?file=busbridge_prj.htm

I am wondering if this could be made with three tubes rather than the  2
1/2 sections of the tube that was shown. I also wonder if this could be
used with an RF amp, detector stage, 1 audio and then this three tube
set up?

Thanks,
Bill Howard
