I just built this kit and finished a couple months ago.  It's a great amp, but it's a complicated build.  You don't need to know much electrical theory, but it requires good soldering technique and following the layout plans in every detail.  I think it's a rather aggressive project as a first attempt at building an amp. 

The kit includes everything needed for a complete amp.  There are 7 boards that will come assembled.  These and all the components (pots, switches, transformers, etc) need to be installed in the chassis and wired according to the layout.  There are around 20 resistors and capacitors that need to be mounted.  It took me about 15 hours to complete the amp according to the layout, then another 10 hours to make the cabinet (no parts are included for the cabinet).

So, 15 hours to save $300. That turns out to be about $20/hr. I think I am probably better off buying the completed amp without the head shell and building one. I have the tools to do that part of it, at least. Thanks again for the help.
