New Aleph 4 - heatsinks anyone?

[apassgear]

I'm finishing my aleph 5.

here are some pics. The electrical layout is by the book. I have detailed autocad drawings if you like.

You have serious sinks on your Aleph 5, I like them very much. How much these heatsink cost? where did you buy them?

Your amps are very very nice, I like that compact layout, simillar to what I did for the Zen amp. I also do layouts in Autocad.

On the Aleph 4 amp I didn't go to a compact design since I din't want to stak the two tranies and wanted some free space for upgrades and modifications, thing that I missed on my Zen Amp.

I will start a new thread very shortly to show this Zen, you should do the same with your beautifull Aleph 5!

BTW, I forgot to mention in my last post that I could send the Acad file where I design the heat sink or to anyone who is interest. only let me know what Rev. you are using.

PedroPO,

I see a copper plate for mounting the power FET?

What size is it?

Is this also a structural part to join the heatsinks?

they costed about €435 six of them, but only 4 are really hot.

they have 200mm height and are from www.alutronic.de. they ship via ups. just email them.

I will post the amp when it is done. meanwille, i'll post some pics.

Collective Order of Fischer SK109 (Pedros Heatsink) ?

Is anyone interested to order some of Pedro's heatsink for 43 Euro/pcs in silver (covered to avoid oxidation)? I will order 8 of them, But 10 is the minimum amount.
