Does anyone have a diagram of a laboratory power source 0 to 50V, adjustable current up to 3A? The kind I make at home.

component values ​​are missing in the diagram. The schematic is correct, the output terminals are not swapped "+" and "-" ?

[borec]

The diagram is correct. The negative pole is really up and the positive pole is really down. You can calculate the values ​​of the components according to the input voltage (transformer) and the output voltage you want.

doesn't the source heat up?
