I dunno, I just cut thru one side of it with a box cutter & gloves & then pack it up & sell it with my other wire.
Theres copper wire in the coil around the small end of the TV tube & some in the transformers & some Ali as heatsinks.
But, this is VERY important.
When you have taken the back off, look at the small end of the TV tube, theres a plug there & inside the circle theres a small glass bit.
Put your safety glasses on & break that glass bit off with a small screwdriver or such.
I just rool it onto its face & shut my eyes & cover them with my arm & start kicking across the end of the tube with my boot a few times.
I don't mean to breaK the tube, just mash up the plug & break the little bit of glass inside/under it.
Once its broken you can hear the gas hissing as the air is drawn into the tube.
Once its stopped hissing its Ok & safe to work on.
If you break the tube while theres a vacuum still in it, the screen & tube will shatter into thousands of long fine spikes & explode like a glass hand grenade in a 10-15 foot radius.
I still can believe I never got harmed the first time I mucked that up & exploded the screen about 2 feet away from my face.
Glass everywhere, 4 inch shards everywhere, even directly behind me.
Nearly shat myself, probably would have if I was busting....
But yeah, degausser-tube coils-transformers-heatsink?-cabling-chokes. All good sources of metal from TV's.
