Default Heat Sinks

Sold in sets of 4, these Heat Sinks are clear anodized and edge finished. They have never been used and are new in the original prepack. The posted price is for a QTY of 4 Heatsinks, I have 4 sets of 4 available. The Heatsink is 6.96" Wide x 2.79" Deep x 8" High, the base is .54" in thickness. Dimensions are equivalent to a ThermaFlo E3093.

I have them on eBay for $180 for a set of 4, but I am willing to take $130 per set of 4 for DIYAudio Members.

These are large and heavy and can be used in pairs for a small class A or large class AB, or used 4 per channel they could easily handle 100 Watts Class A at Ambient plus 25C. I am running a Stereo MiniA at 20 watts on 4 of these and it runs at ambient after hours of use.

Payments would be accepted via pay Pal, contact me for shipping costs with your address if interested.

Thank You
Anthony

Do you know the heat dissipation of the 66427 pictured for the 6" piece? I cant run rtools and model it on my iphone I'm trying to figure out if 1/channel is enough for an F5. How much for shipping to Winnipeg, R3T4C5?

What is the power dissipation per device? How many devices on each Heat Sink?

Your probably good for about 35/40 Watts of dissipation for each Heat sink @ 20 to 25 Deg above ambient. So two per F5 channel I would assume, this is what they were originally specified for when I ran the group buy.

The 12" ones are good for about 100 watts of dissipation, which is why you need two for an Aelph 2 Mono block amp.

BTW if you need any parts for the F5 like caps, devices or transformers drop me a line.

Would you entertain the idea of selling them in pairs? By the way, how much does these weigh? Thanks!

Well I only have 4 of these and I would rather sell them as a set of four. I have not had any other requests for a pair. Though if I get another request for a Pair, I will reconsider selling them in pairs.

They're not that expensive in UK.

Have a look at http:\\www.rs-online.com
