[hpsdr] How to fry Penny/Ozy

[Charlos Potma]

Hi All,

Last night one of my old and trusted HP power supplies failed in a spectacular way:
the output voltage went from 12V to 40V. The result was a sputtering and
smoking Penny output stage, popped capacitors on Atlas and
some components damaged on the Ozy board.
Lesson learned: do NOT trust your power supply. I need to build
a dedicated supply now with overvoltage protection on all outputs...
