Constant Current Dummy Load Revised

I revised my EEVblog inspired constant current dummy load.  I was able to improve the performance under higher currents by shortening up some of the traces on the pcb and adding a couple of components. Some of these PCBs didn’t get the back silkscreen of the Golden Driller (or “Tulsa Man” as Dave called it.)

I sold all the kits I had… Hopefully I’ll be able to put some more together soon!
