The thread below, Attracting non-Audiophiles, inspired me to dig out an old PCB board I ordered years ago. The board is the original Zen amp designed by Nelson Pass. I realize this amp is in its 9th stage of develolment, but I thought it would be a great project for my son.
My son is only 7 but loves putting together electronic kits - mostly LED flashers and such. His eyesight is so much better than mine and he's deadly good with a soldering iron. He soldered all eight pins of 555 IC without any trouble!!! The Zen board is well laid out, with the traces and components not nearly as packed as on some of the projects we've completed. So, it really should be an easy build.
I need a power Tx from Parts Express for this project. So, do ART members get a discount (code????) or does ART receive a donation? Either way is great. I just need to know......C

That's nothing... when I was a kid we lived in Tektronix's back yard. They used to (may still) have a "Tek Country Store" that was open (IIRC) Wednesday afternoons. You could go in and by non-working scopes, modules, tools, surpuls parts, wire, etc. One time a buddy and I bought this giant rack size CRT tester. It would hold, I think, 10 or 12 5" CRTs for testing. Consequently this thing had a monster serious power supply.
Well, my friend and I talked a stranger into putting the contraption in the back of his pick up and taking us to my house. There we powered it up and quickly found that there is, in fact, a breakdown voltage on VOM probe leads. When we hit the power switch, and after a few relays and stuff clicked on, POW! Juice hit the HV rail and my buddy went flying across the room. Landed against a concrete wall. Thank goodness we were 16 or so and survived such mishaps. Wiser now, and the buddy survived, too!

Haha - When we were teens, my brother built a BIG Tesla Coil, and we had all sorts of fun with it, also using it to play around with Jacob's Ladders, etc. I used to like to try to draw the biggest spark out of the Tesla Coil possible, and one humid day the "insulator" I used in doing so, a wooden yardstick, turned out to be not quite such a good insulator after all, and I got whapped by roughly .75 Megavolts. Thank God there wasn't too much current behind it, but there was enough to send me back a few feet. I also got knocked back across the room by residual voltage on a CRT once. That was a doosie, too! Definitely something one remembers...
