This is a LM338 based power supply (with Short Circuit Protection) which is not complicated and easy to build. I am using the supply for a long time, have no problem yet. Only current adjust is missing but I overcome this situation by using an LCD panel ampermeter. There is no PCB for the circuit. I took a 3×16 copper plate and strip the unused areas by a knife. If you want you can use analog meters instead of LCD panels.
