I want to build a bench power supply, and am looking 'round the net for a
good circuit.

Requirements: 2 outputs, adjustable v, adjustable i, v & i meters (or
digits). Prefer 30v max, or similar. Preset v selections (5, 12, 15, etc.)
would be nice.

Here's one I found, complete with the designer's smiling face on each

What's your favorite circuit? Features you like that I haven't mentioned?

Thanks,
