Notes

1. This regulator in circuit comes in a TO-3 case and must be used with a large heatsink. You should be to mount a small fan to blow air across the regulator .
2. For the filter capacitor is large. The filter won’t fit on any board that bolt it to the case.
3. You can, of course, add a volt and amp meter.
4. Since this project operates from 120 VAC, you must include a fuse and build the project in a case.
