Get real already. Real? The reality is, adjusting knobs recklessly on a power supply can lead to damage.

The external component count is low, and obviously one would verify the output with a voltmeter or something. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
