Heasinks 300 x 150 x 83mm anyone?

[mbrennwa]

Hi all

I am planning to get some heatsinks for an upcoming power amp project. I found it's not trivial to get large heatsinks at a reasonable price, especially if shipping costs are factored in.

I will get some 300 x 150 x 83mm heatsinks, black anodized (profile attached). Price is CHF 63.– including delivery to my door (which is in Switzerland/Zurich). If anyone is interested to join in, I can order more (and maybe get a better price).

Let me know if you're interested.

I could be interested but I would want a bigger size.

400mm x 200 x83. I would be interested in a pair of those!

Could you share the source of these heatsinks?

I don't think we can easily mix different type / sizes.

Could you share the source of these heatsinks?

Found them at amelec.ch (profile PRO1267).

I found a number of similar alternatives (but not for the same price, shipping included):
Austerlitz KS 300.6 (from transmetra.ch)
Seifert KL-271 (from vibratec.ch, these are almost the same price as Amelecs, but no free shipping)
Fischer SK-157 (way more expensive than the others)
GD Rectifier PS385 (from gdrectifiers.co.uk, these are the cheapest, but shipping from UK is super expensive)

Is there a way I can fix my stupid typo in the title of this thread?

Hello,
I just found a source for heat sinks.
Made one order and was very pleased with their products.
They will provide almost any size you need.
I'm not connected with the company, just a customer.

Would it be possible to get them to split the combined order for delivery to different destinations?

chf63 (£41) is not cheap, but they do look very good.
What is the Rth s-a?

brought over from the duplicated enquiry.
