[Elecraft] EC2 Clone (Was The 1500 watt amp)

[EricJ]

If you can build whatever you want, you can easily build the enclosure. 
Here is an EC2 clone I built last week in about 6 hours. I made the side 
panels with a hacksaw, file and drill press. The front panel I cut and 
formed with an inexpensive 8" shear/brake. This one is branded Grizzly, 
but Harbor Freight has them as well. I didn't use the Elecraft 2D 
fasteners because I only had 2 on hand and didn't want to make a bunch 
of little fussy pieces. I used 4 long sections of 1/4" square aluminum 
stock and drilled them with the same hole pattern as the 2D fasteners. 
The front panel will get painted after I drill and punch it for the 
current project.

The smaller K1 enclosure is nearly the same design (slightly different 
top cover) so it scales down easily. It would scale up for a large amp 
just as easily. The cost of the EC2-clone was about $4 in materials 
(0.080" and 0.050" sheet and 1/4" bar stock). All can be built with a 
hacksaw, file and a hand drill. A bandsaw and a drill press make it more 
precise. A shear/brake makes it even easier.
