If the parts don't cost too much, I can whip up a PCB and test it.

Interesting concept although I can think of better housings than a glass jar. Something a wee bit less breakable.

Yeah.. I think they were going for the insulating properties of glass there.

Ah, well... plastic's as near to an equal isolator as you can get to glass and is (generally) far less fragile. Hell, Bakelite is less fragile although I dunno where you'd find commercially produced blank Bakelite project boxes.

It would have been interesting to compare them & see just how far off they are especially with some Active PFC PSU's!

Yes. One of the last commincations I had with Dave Hammock before he disappeared from the web was how a major brand single +12V rail PSU wasn't shutting down when shorted. We were literally arc welding with the PSU. Hopefully Dave's absense isn't due to the fact that he got over zealous with the welding.
