I developed the mod originally and started a thread on it on the 4hv.org
forum. It grew out of some other work I did modifying an old 15v switcher to
use as an 0-30v bench power supply. I reckon the mod works on just about any
power supply controlled by a TL494.
I was going to write a web page on it but I never bothered due to lack of
interest and worries about safety.

Kreso, (and anyone else) be careful, the filter capacitors on the output are
only rated 16v. You don't want to be digging them out of your forehead.
