Do you think this is a safe amp kit? The creator believes it's "probably the safest amp kit."

I don't get it
Why would you want that?

..and you've got an educational package


That would be it's big selling point for school projects, I'd imagine. But IMO, each one of those banana jacks will behave like a cold solder joint, given time.

You're supposed to stick it in an enclosure when you're done.

All those connectors and extra wire lengths are not a good idea, IMO


It looks like it would make a good school educational project, but that's about it


Why do you need all those clear plastic boxes if it is going into an enclosure anyway
You would be better off just making your own board and sticking it in an enclosure


Just my .02

His marketing is based on the absence of soldering.  I'm just curious to know if anyone sees any safety issues with the design. But I guess not so far...

mine's nowhere near as safe... but far more flexible.

he should use cat III shrouded test lead jacks - no exposed conductors. yes it's educational, yes poor slobs will get bit.

Yes, I read that thread before posting here as an experiment to see if similar views would arise. 

Cool rig Pete.

Awww heck, back in my high school electronics classes, we used to charge up the breadboard caps and toss them to unsuspecting nubes.  Things like that used to build character!  Now it would get you expelled, thrown in jail, and sued - along with 24 months of sensitivity training for bullying and a week long apology tour on the news with the Principle and a long stream of letters sent home to the parents.  Nothing like a non-beverage Jolt to wake you up in the morning!
