Colin's patented design for a head amp
Colin generously asked me to post these files in connection with a head amp originally for the Magnum amplifiers. Colin holds a patent for the design.


Plus a Spice file.
You can get Spice from http://www.linear.com/designtools/software/#LTspice
I'll leave it up to Colin to explain further, and to answer questions if you want to build it.

Having heard some of his 'babies' again, I can only recommend someone take the plunge & make this. In all liklihood, it will be awesome.
