You get used to stuff like this pretty fast on the speaker amp side. The first day I was working at Sumo, a TO-3 MOSFET (big metal can, about 1" x 0.25" in size, with big mounting flanges on either end) melted down badly enough to blow a hole through the top of the metal can and send a 2' long jet of molten silicon right past my ear. I started wearing safety goggles after that.

And now we know why you guys say you don't want to do electrostatic amps!

Ear goggles? tongue.gif

I've had molten aluminum blow through a face shield before. Ear goggles might not do much... :blink:

Yeah, perhaps it's best to just work from behind a bunker. biggrin.gif

I've had electolytic caps blow in front of me a few times........  not recommended.

Nope. Here's a preamp I did back in the late '80s. You can see the polarity markers on the tops of the caps in the array. They're supposed to alternate two rows to the right, two rows to the left, etc. Check out the cap on the right in the third row from the top.

Was in a hurry to get it built so I could run it over to the photographers. You can imagine what happened shortly after I plugged it in once I got it back from the photographers. My faux pas preserved forever in a Kodak moment. biggrin.gif

Yeah, memories   memories and lessons learnt.

Once you've checked everything you'll assume that everything is correct.

 

That's when it's time to double check your assumptions.

Check.

Or better yet, have someone else double check.

Check check.

On a more informative note: I used to be a computer programmer. As I was also manager of quality I was in the habit of assigning a second programmer (not associated with the given project) to do joint walk-throughs with the app's programmer/team at key milestones. Particularly with single-programmer jobs this could be difficult as - back then anyway - there's a lot of creative scope and variation in how programmers code. It's not always easy to understand someone else's design approach and decisions.

In other words, sometimes having someone else check properly looked like it could take so long they would've coded it faster themselves.

I imagine things have become much more systematic and standardized these days.
