Heatsinks

[josefr]

Hello everyone

Here is my next question. I going to build class A amplifier - about 20-30W per channel. So I need good heatsinks. I found something like this in the picture. So if I used 4 of the biggest ones, 2 per side, 10cm in height would it be sufficient

But there is possible problem - they are not anodized - pure aluminium. Did someone of you anodizing by himself - or mayby link to "DIY - anodizing heatsinks" 😉

But price seems good - 4 x 16z³ is about 16$ - for them all 😀 - is it good price?

OKI - forget about anodizing.

Is there a big difference in heat dissipation between black anodized and non-anodized aluminium 😕

7% less without the anodizing

Well - I have downloaded this page before but I didn't read it all - sorry if I bother You without reason




And about anodizind - I found it is quite simple operation - but dimensions of that heatsinks are to big to process them in my house
