I'm wanting to make my own linear PSU for my radio needs. I already have a metal case to store the components. My main issue is putting out enough amperage at 13.8 volts. http://www.physics.unlv.edu/~bill/PHYS483/power_supply_info.pdf Just for example, the above uses a 12v regulator but I'd imagine it'd work for 13.8 as well. Since those individual regulators can only handle 1.5 A, could I connect the regulators in parallel to allow more amperage through? Any thoughts?
