Whats wrong with this circuit

Whats wrong with this circuit I cant get it to work. I got a 50k 10 turn pot instead of the course and fine and 1 10w 1 ohm resister instead of the 10 single resisters, the rest is the same.

The designer put a forum topic somewhere here.

You could take some voltage readings and put them here.  That would helpful.

Also, the FET has to be a MPT3055VL.  It is correct in the BOM from his website.
