DIY head amp


Has anyone built any one of the head amps designed by Marshall Leach as found on : http://users.ece.gatech.edu/mleach/headamp/ ? What do you think about the Common-Base circuit? I'd be using this to boost my Dynavector 17D2 MkII. I'm interested in your thoughts.

Point-to-point just as the circuit is layed out including a 9 volt battery. I saw the Markof version on eBay and it used 2 AAA batteries.
