Good inexpensive heatsink source?

[Doovieman]

Anyone know where to find nice big but inexpensive heatsinks? Preferably, not used before... I've seen some other postings that show huge sinks...I'm looking for something on the order of 3 inches long (maybe even a bit less) and 6 inches wide. Thanks.

I've used these:
http://www.bgmicro.com/prodinfo.asp...6&prodid=ACS1395&page=1&cri=heat+sink&stype=3

I ordered 6 of them and they were unused, but about half of them had minor surface scratches on the ends. (You could see the bare aluminum, but no percievable amount of metal had been removed.

You can see them in action here:

Edit: If you are interested in these, I can email you about half a dozen close-up photos of these.

You call that big?

I bought a couple about that size from BGMicro for 3.99 each - cat. id ACS1395. Planning on using them for a gainclone (or 2). The only problem is the fins run the wrong way for me.

Might be suitable, check out:

I see seangoesbonk beat me to it.

Re: You call that big?

I beat you to it!

I used a pair of these in a LM3886 quad channel gainclone. (38wpc, 28Vdc rails) I use it with a pair of Tangband full-range fronts and a DVC Adire Shiva.

I was worried about the orientation of the fins, but it barely gets warm after a couple hours of use.

hmmm...those are nice but I'm looking for something with the fins running the other direction and preferably silver. Any other suggestions? Thanks,

Doovieman

That apexjr is pretty hot. They're sinks aren't quite what I'm looking for but they're definitely a great resource...Thanks!! Any other suggestions for sinks?

You are in Berkeley, right? Check www.halted.com. If you havbe the time, the best bet is to drive to one of their shops. One is in Santa Clara( Lawrence Expressway and Central), one in Rohnert Park (just off 101 between Santa Rosa and Petaluma) and Sacramento.

No guarantees but there is a good chance you might find something.

If Doovieman doesnt want the 2 black anodized sinks, I'm interested as I've been needing something along those very lines for the gainclones I'm building.
Steve, if he doesnt express interest, could you please email me?
Thanks,
Jonathan
