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.
I just wonder how you're going to assemble the unit (circuit board or point-to-point wireing) and what power supply you're going to use (it's important) or just 9V battery is you think enough?
