Well, well… this blog seems to be updated weekly. Anyway, todat I’ve received the heatsinks and they look stunning! I had some difficulties because the delivery company could not deliver the package on a saterday. So instead of sending it to my home I had to send it to my work (which is almost one and a half hour by train/subway/walking). Good thing I do some exercise, these heatsinks weigh around 10 KG total

Well… I’ve payed for the heatsinks today, it amounted to around 198 euro’s. Fairly exceptable compared to Clofis’ pricing, but enough about that, I will try to find the time for ordering the PSU capacitors at Schuro (a company specialized in audio components located in Germany).

A small update of the Aleph-X design. Now rendered in Blender and YAFRAY (Yet Another Free RAYtracer). This time with a sun as a lightsource instead of a regular spotlight. One thing I must say: I have problems with te lighting, the usual settings: 1.0 Energy for the lighting is not enough. I had to amplify this at least 5 times (which is not needed for Blender’s own renderer).

Heatsinks and case design

Ok… What’s the status on the Aleph-X?
I never got a reply from deltour heatsinks, so I will verify the price and go for the Australian heatsinks. These are, however, slightly below my ideal heatdissipation (0,279 K/W each instead of 0,21 K/W) so I have to settle with a slightly less powerfull amplifier. It will still deliver 99 Watt at 8 Ohm with a peak of 117 Watt at 6.5 Ohm.

Because of the change of heatsinks I also redesigned the case (it’s still early design):

Here’s also a schematic of the powersupply: Schematic
The resistor represents the load of the amplifier, which in the simulations would amount to: 22 Volts @ 6.1A (which is more then I will actually use).
