This might be a stupid question.......
Im very new to scrapping and im messing around with a old stero I have. On the inside of the stero is this heavy box. Its about 3x3 and looks like it has a copper band around what apears to be a circular type thing that sticks out of both the top and the bottom. Does anyone know what it is? Is it safe to be messing around with it? What do I do with it? Im sorry if this question is terrible but like I said Im new to scrapping. Today is my first day actually. Thank you.
