240 Ohm may not load the output appropriately on some regulators. R2 may need to be decreased to 120 Ohm if you experience voltage drift at light loads. Since this project operates from 120 VAC, you must include a fuse and build the project in a case.You can, of course, add a volt and amp meter.It won't fit on any board so bolt it to the case. You may want to mount a small fan to blow air across the regulator (I did). The regulator comes in a TO-3 case and MUST be used with a LARGE heatsink.Wire, Line Cord, Case, Binding Posts (for output) It is easy to build and the parts are realitively easy to find.ฤก4000uF or 10000uf 40 VDC Electrolytic Capacitor It produces a well filtered, variable 1.2-30 volts at 5 amps. This power supply is great for powering all kinds of electronic projects. When working with electronics, you always need one basic thing power.
