Fred Nachbaur died a few years ago unfortunately but some his work and design's are available here for those interested - http://www.dogstar.dantimax.dk/tubestuf/index.htm
Hi Andy, on the response graph the upper, dark, trace is the output response curve and the units are the left hand vertical db scale, the lower light curve is the phase shift, units are the right hand vertical scale.

I am busy this weekend but will answer your question as to what I think of the design monday.

Peter
