Well, I haven't seen the first group buy so I don't know what it looks like. I'm considering using this heatsink to my amp and trying to figure out the best way to mount it on my chasis.

Could you give us estimate cost per foot, so I can set aside a budget for it?

Thanks,

Fred
 
Thermal Resistance for Russ's new Extrusions

Using the volumetric method, I calculate a thermal resistance of ~ 0.30 C/W for an 80 C temperature rise for a 1 foot long section. For a Pass amp application, given an ambient temp of 22 C and an average heat sink temp. of 55 C, this sink will safely absorb ~ 90 watts continuously. (Note, I derated for the lower temp. rise using Thermalloy's table).

Perfect for one side of an F3 and a 9" tall one will work great for an F5. Good luck with your extrusion, Russ, i know you'll have a ton of buyers !!
 
Good news, I got an e-mail from BarredBoss and the Sinks are alomst here. He told me the per foot price woud be in and around the $45USD mark, not cheap but surely not the most expensive I've seen either. I'd like to see them before I spend $360USD on the heatsinks for 4 stereo amps. Good news, bring'em on BarredBoss, Peace.

Keep well all.

Might be good for you US guys, but for Canadians, if you count shipping and taxes, they are to expensive. Ro-theta here in Toronto comes to about the same price per foot, including tooling charge and overnight shipping by FedEx.

Wonder why only one pc. per flat rate box? To heavy? I got in the past up to four 1ft. long 5 3/4" wide sections in a box... With two sections per flat rate box, we may talk about...
