Put this together real quick during some holiday downtime and it’s been “always on” with my little practice board in my workshop. I’m in the process of redoing my big board and this will move to that one when I’m done. (Let’s be realistic about this hobby, I’ll probably manufacture this into an opportunity to build another one.)

This is my first 1590A build and I made a few mistakes/lessons learned. Most of it stemming from me neglecting to “measure twice, drill once.” But with some of Barry’s hookup wire I made it work. I really enjoy having so much boost on tap with such a small footprint.
