In the process of building an amp I've been using crocodile clips in the psu section.I'd been experiencing some odd behaviour when checking actual voltages on test.I put this down to house mains variation.After all it was making sound.But last night I noticed a mini thunderstorm in the jaws of the clip lead at power on.Wish I had a recorded footage of it.Amazing to see!
On pulling back the protective covering here's what I came across.The maker didn't even bother to solder the leads.Penny pinching?
First pics are of the offending sod of a lead,the rest my repair job.

Yeah, pretty standard practice for that kind of item. You may even find that the "copper" of the wire is in fact magnetic....
Probably some advance in the quantum material physics....
Cheap 'test leads' with croc clips on the ends are almost always badly made. Even if they are soldered you can't be sure it is a good joint.
By the way after soldering the leads I noted an increase of 20 Vdc in my B+ supply.Interesting no.
I generally buy Mueller alligator clips and make my own leads. Their clips are little works of art, with jaws that mesh perfectly.
