Extreme speaker connectors

I don't know about amps, but some of those connectors look like they'd be more at home on the front of an arc welder!

Maybe they would come in useful for someone out there trying to make an ultra-fi welder?






Isn't copper oxide green? This is a favourite science experiment I remember from days gone by - you put copper in sulphuric acid and you're left with a green power that's copper oxide?

It is. Pennies - even Canadian ones -- aren't pure copper. There is some green oxide in the pile, but the predominant color is "crest-toothpaste-blue".

Copper oxide is red or black (brown?). There are two types anyway. Green surface comes from sulphur(?).

These connectors aren't for domestic use. They are for use in the heavy industry!

Copper oxide is black. The green is from chlorine (it's called malachite).

Take a quarter cup of vinegar and about a tablespoon of salt and mix them together in a glass container until the salt is dissolved. Take an eyedropper and put some drops of the liquid on some pennies and let the liquid air dry. It will leave a blue-green film on the pennies.

The same solution is excellent for removing copper oxide and copper sulfide. Just make sure you rinse it off thoroughly afterward.

I was, erm, kind of joking.

...just to set the record straight here's a picture of the stuff, Cuprite Cu20 (I was wrong - it is red/brown)

Eeeewwwwww! That looks like some gangrenous festering wound! Get it away! Get it away!

These posts are cool, I've been
looking for exotics. Is there
a place to "click and order" from ? LOL

The only thing I was able to find
was this one, cost about $3 each.

and the Neutrik, 40a contacts.
using the 4 contact in parallel for 80A.

Is this the same connector found on
passlabs stuff?

Sorry, this type of component is for industrial use, not comsumer use. If you anyway want these beasts, get in contact with Pulsteknik in Sweden, see above.

Hi,

the last time I saw them was in a flyer in 2009 and an old website of 2011.
The link on that site directs to the actual website which dioesn´t list the connectors any more
Seems they don´t offer them any more.
Maybe I´ll phone them soon.
