Another Aleph X up and running
After some months working quite hard on them (specially for the metal hardware), my Aleph X's are both up and running.
Voltage at the fets: Between 17.5v and 18v bias: 7,2A AC Gain: 54% Number of fets: 8 The DC offset between the outputs is between 18 and 25 mV and the absolute DC offset 350mV after two hours of use. The temperature is fine: after two hours, I still can touch them with the hands without problems. The sound is really amazing. They are driving a pair of B&W 803 and the preamp is an Aleph P1.7 Xavier |

Hi,
nice amp! Very easy way to make a chassis with those edge connectors. Where did you buy those? Do they come in different sizes? William

I bought them in a local hardware store. They are supposed to be use for making glass tables or shelves.
The width of the square tubes is 25mm and you can get the tubes cut at any lenght. They have several different edge connectors (3 or 4), feets, etc. The structure can be mounted without any screw. |

Hi!
i noticed that you used mills resistors...isn't it? Another thing.....on your picture i can see just a part of your loudspeakers...are your speakers B&W?! they really look like! I don't know if oyu gave the necessary time to the amp to burn in all the new components.....how does it sound like so far? What stereo parts do you have?...cables...source....speakers....? Best, Stefano.

Nice job!
Very clean!
I also like those corner connectors. Very handy... I'd be interested in your comments regarding the sound. Great work!
