Thanks guys,
as soon as I have progressed i'll show some more details...
this amp is just getting heavier and heavier, I think that I am about 30Kg by now and the faceplate and rear plate aren't there yet! I think I'll have to put handles front and back side, or I'll never manage to move it to the living
see you soon for the next steps!

Very Nice
I'm not familiar with the Krell But, it reminds me of a JC or I guess ML-2 or something.
Super Job

Hey thanks Flg,
that is almost a very nice compliment ,comparing my mechanical work to Mark Levinson is just very satisfying, and I have to admit that I was very inspired by the ML-2 , very happy that you noticed

My goal is to finish the amp as good as it began, not easy thought, as now it's getting more and more complex inside...
and I still haven't matched the fets "in situ",the hardest job still remains!
thanks for your support and nice comments, it really encourages me to make a nice work, especially because I know you are all as impatient as I am to see the thing finished

Hi Vince,

Beautiful looking design!

One thought to consider as you make the chassis. Leave a lot of space inside the box for natural air flow. Some of the other internal parts will experience shortened lifespans with additional heat.

Here's a pic of the my Aleph30 using BrianGT's boards. Simply sounds great.

Nice work so far.

[bobsinclar]

here is the work on the back plate almost finished ...will show the massive front pannel tomorrow...sort of SAE X series design, but with a bad look
I hope i'll be able to finish it this week end...I will come with the picts azs soon as everything isassembled...
Vince

 

[bobsinclar]

here is the face plate, at least installed...I fired up the psu and the soft start circuit ...everything is ok...29volts...enough caps to let a 220V light on for about 1 minute after amp is turned out (about 400 000 microfarad)

here is another view
