Description: - Variable power supplay 0-50V / 0 - 2A

Source reference: - Elektor 1980-07-08.pdf, p. 86 (76) - No PCB ref. no. - National application note.

This is functional similar but not exact copy. All dimensions were estimated by eye. Tried to use similar component placment as much as posible, but using only Kicad standard PCB component footprint library, so dimentions may very.
