[Elecraft] The amp I would like to see Elecraft build.

[Gary K9GS]

Or better yet, do what other SS amp manufacturer's are doing, use 
surplus HP Proliant server power supplies?  Here's a 3KW one/50V for 
$30.00.  There are warehouses full of these things available.

http://www.ebay.com/itm/HP-ESP120-2950W-Power-Supply-226519-501-406424-001-253232-001/391114939625?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D37577%26meid%3D7a666926576944989b8c1bc8c2e7ec53%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D122038440431

They have other current capacities available.  These can be run in 
series or parallel too.

Sure beats re-inventing the wheel.
