zener diode

You might have guessed it from the diode arrow symbol orientation.
Some manufacturers avoid the confusion by using +/- notations instead of cathode and anode.

Mark,

them others didn't say "What is", all of them disqualified for the last couple of decades.
I suppose a Z-diode would scare the bl... out of Dracula too.

Nice!

Have you had time to etch and build the thing? Do you have some special heatsinks since you decided to have output fets on both sides?

I'm still waiting for the laminate to arrive - 1 layer pcb seems to be difficult to obtain in Denmark these days...
