Now i usually don't mess with crt's but when someone has a big load for me, and lots of good stuff, i say sure i can take that. so i did notice that this one was bigger then normal, more square then normal. i got it a few weeks go by and i finally got to it yesterday. when i pulled the plastic shell of i was like WTF. All the metal casing, and brackets were alum, and it has a huge chunk of alum for the heat sink. but wait it gets better!! There was so much copper wire, i couldn't believe it. Usually there's one or two thick cables that you can strip, this baby had 4 meaty ones and 4 smaller ones. I ended up with 5 lb's of BB copper!!! wow i wish all crt's were build this way!
