Yet Another Aleph2!

kenny_(00)_ · 21st May 2003, 03:58 PM

Hi everyone! This is my first post to diyAudio, and I know u all dread seeing another Aleph amp appear here, but I just wanted to share my joy with you guys! I can safely say I finished most of the amp except the wiring, haven't thought of how I should tweak it yet. Please feel free to criticize my wrongdoings! You can also see the description here and other projects I've done on my homepage....

Thats a nice looking amp. Very clean. I never get sick of pictures.
You will end up with more caps.

Hi,

nice work,
but I'm not sure that only 4x15000uF are enough for one channel Aleph2?

Hi again, the caps were salvaged from another amp. Though I didn't plan it this way, there is enough space for another bank of caps if i need more. What do u guys think of cerafine caps 22,000uf@50v? I think I would prefer a more punchy sound like the X series, if everything else can be recycled, maybe a drop-in driver board to make an "XA100"?

Ha, but Singapore is one of the most difficult countries in the world to get a chassis made! The casing's design is actually pretty simple, but drilling/filing the holes is definitely not! And they are rather expensive too. I had bought the heatsinks surplus, then had them reanodised. Turns out this arrangement is good for easy modding

The I/O power switch and powercon were last minute additions as i couldnt resist them!
