Today I was processing hundreds of TV yokes that I have been putting off. In the process I found a few yokes that had aluminum windings.
Also was cleaning heatsinks afterwards, and found a few brass heatsinks that had chrome plate on them. Hadn't seen a brass heatsink before today.
Just a heads up.
Wow... never saw a yoke with aluminum windings. That sucks.
Also, I see the word "yoke" spelled "yolk" so often, that "yoke" doesn't look right! Kudos for getting it right.
I think most people wouldn't have the chance to see if it aluminum or copper, because for most yokes, smashing them up to bits is easier. I was using the angle grinder to cut the glued on windings off the ferrite.Quote:

Are you sure they are brass and not copper...never saw a brass heatsink. Any pics? What did it come out of?
Honestly I don't know what it came off. I have a dirty heatsink bucket and I clean them when it's full. I will have to dig it out and post a picture. It felt heavy so I hit it with the grinder and found out.Quote:

Here is the brass heatsink. The middle hole has that white goop on it like most other heat sinks have. Sorry if quality is bad, it was taken from an iphone.

^^^ thats copper
So I suppose now there's a yellow copper?Quote:

The motor driver chip brass heatsinks are normally soldered to the board & come from 70's Tv's. They may also protect everything else on the board from the EMF (electromagnetic field/force) the chips may make as they cover the whole chip.
A interesting distraction when scrapping.
Its copper at the yard i sell at, they cut it, looked at it and said number 2 copper since it was plated.
I find thinner ones from time to time, when you bend them the silver color plating just flakes off revealing the brass underneath.
There is tinned copper, but this is clearly tinned brass. You're getting a good deal for getting #2 copper vs brass price, though.Quote:

Get rid of the tube? Check your local Goodwill, I did some Googling and it looks like Goodwill has the Reconnect program in Pittsburgh which accepts computers, etc. Call and ask them. There is also many threads on here discussing the exact question you just asked. Use the search function, and most any questions you could ever have can be found by using it.Quote:

Yup thats brass...good find. Thanks for the picture. Learned something new today.
Here in CA i get 6# for tubes after i strip em
Pull the insides and put the back on with screws and deliver them to the local Goodwill (check with them first).Quote:

You can put them back together, at least a few, and bring monitors to most Staples stores and monitors and t.v.s to most best buy stores. Check the websites for details.
How do you manage breaking down that many yokes?Quote:

That's a new one!
I do the same thing but don't get many tv's or monitors any more. The tv yokes are a little harder because the copper is wrapped around the ferrite and have to use a hammer and smash them to get the copper off. My yard is ok with the glue as well and on electric motors it's ok to leave the string on the copper it goes as #2 copper.
Best Buy, Staples, Goodwill, or Eloop (Ewaste Recycler, Plum, PA) will not take any TV that has anything missing from them. I have made my calls to all of them to find out what to do with my scrapped out TV's since PA passed the new ewaste law. Dlubak Glass in Natrona Heights told me that I could drive the CRT tubes to there OH plant. Eloop told me to call 1-800-GOTJUNK. I already visited with my local State Rep and haven't heard anything from him. I have turned down about 15 TV's so far this year because of this new law, but I do have some TV's here that I need to scrap out and get rid of, and would like to do it properly.Quote:

Found my first brass heatsink today in a LCD monitor. Not a huge deal, but I just thought I'd share. I thought it was some kind of plated steel at first, but a quick cut with the dikes showed brass.

Smack the ferrite with a hammer inside an old feed sack or something similar and pick out the copper. Then you can pick out the ferrite with a big magnet and throw it into your shred pile or an old microwave carcass.Quote:

The plastic is already bagged up to recycle/throw away, which ever.
I always check my heatsinks. I have found a lot of alum plated copper ones
That heatsink comes out of a crt computer monitor. Not all of them will have it though.
Wow, never had aluminum nor brass in scrapping a tv in those areas.
Dude, where is your gloves?
Lucky you. I need a new yard.
Hey Ewaste, thanks for a smooth transaction, got my money today.Quote:
