    Transistors, are they worth anything?

    I have tried searching through old posts and can't find a solid answer. Are regular transistors, such as the black ceramic ones attached to heat sinks or the black ceramic cylinder ones worth anything? I've seen a few YouTube videos saying they are and a few sources saying they aren't.

    The one with the metal, the metal is copper, scratch one and look. Currently I am saving those until I have enough for me to mess with. Mike

    Now go beat the copper out of something, Miked

    Awesome thanks for the info! I havent found any metal cased ones but probably have about a pound of the ceramic copper ones from crt screens and light bulbs I've taken apart. I javent been super diligent about saving them but maybe ill grab them when I see them now.

    I love the day I found out they had copper. I now save them off every board I come across with them on there. Anything with a heat sink in my experience. (I'm referring to the top one).

    I imagine once I fill up this bucket with them, I'll figure out who to sell'm to. lol.

    I rip off the top sort of transistor, the one with the copper backing heatsink on it.

    I have a theory on Copper that "If its about the size of a 1 cent coin, its worth 1 cent". Have over a gallon of them.

    A while ago I got a tin can full & chucked it in a fire & charcoled the plastic & sieved out the Copper backing & Copper legs from it later on. I got a few Lbs of messy Copper.

    While it dosn't look good, it weighs up. I can pour it into something Copper & cap it & sell it like that. (I will explain to the metal buyer first what I have done, to be sure.)

    The copper ones are #2 copper, just throw them in with your copper. How easy is that.

    Could someone confirm if that correct and generally accepted as #2 copper in most yards? It seems that pretty much all the yards I've seen have not much tolerance on contaminated copper (none on #1 and maybe some soldering or burn on #2 and that's it) and they won't be happy to see ceramic in their copper bins. Also, if I cut them out of PCB instead of desolder them, do I lose just a bit of copper each time or buyers can seriously be displeased that I did that?

    Think there are different definitions in play. Have seen a few times where people put something less than 50% copper and call it #2. #2 officially has to be less than 1.5% contaminated and that 1.5% can't be, for example, steel. But local yard shorthand can mean everything from Cu breakage to actual #2.
