Not a specific answer to the question, but I've been planning to try the
"Simple 2-diode doubler" in this article...
What say the experts? How does it stack up to the JFET design being
discussed? Also, I'm visually oriented; finding it hard to follow the
JFET discussion. Any pointer to a schematic of an implementation?
