This supply is a 10-15V regulated (LM723) power supply with 2N3055 pass transistors and computer-grade filter caps. The interface provides APP and Banana plug access to the supply. A front-panel mounted fuse for over-current, and a on PCB 15A fuse for over-voltage protection (SCR + Zener).
Amp meter fullscale at 15A, voltmeter fullscale at 15V.
Clockwise from left: Voltage pot (10-15V), Amp meter, voltage meter, LED power light, Anderson Power Pole jacks (2x), Fuse for over-current, banana plug (0.75" spacing).

A lot of the parts are free/flea-market sourced. The most expensive part is the transformer (18 VCT @20A), the rest of the parts are simple components found at flea-markets, junque boxes, mouser.com, or local sources. PCB's were hand etched. Stand-offs and aluminum work were hand machined. Panels were hand-made.
