new 10.125" wide heatsink - Page 2

Yes sir a price per foot estimate would be nice so I could budget for 4' for my F5 project. Let a brother know Barredboss, it would be an ideal size.... Peace and keeep well.

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 !!

any updates to this point? I really wanna build my F5, and barredboss was a great buy for my previous purchase!

speakrsrfun · 26th May 2009, 12:28 AM

Yes I'm also waiting patiently to find out a price, F5's and a few Alephs awaiting heatsinking.....

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.

Russ has these new Dies listed on Ebay for a BIN price of $52USD/ft

I'd need 6 feet for my current projects, wonder if he'll do multiple pricing LOL....

Here's the link if your intrested as the heatsins are quite nice.

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...

I have a US drop site in Niagara falls (right over the bridge)

I would be willing to get a groupbuy together if you guys want and drive over to pick it up

i'd be interested for sure.

I wish there was a cheap way to get Canadian or US products across the pond.

Is there a surface route for heavier/bulky stuff that is cheaper than what the retailer/manufacturers charge?
