Hello!
A long time ago I started building two Aleph-X mono blocks. Last week I've finished this project and here are some picutres:
The amps:
Input Stage:
The first test:
Soft start and auxilary power modul
Output Stages are finished:
Main Power:
First mounting of all case parts:
The backside:
Inside the amp:
Some technical specs:
70W/4 ohms load
16 volts per rail
12x IRFP240 per unit (IRFP044N wasn't available from my distributor, so I changed the order into IRFP240)
PSU: 120000µF per unit
PCBs are layouted and fabricated by myself
case was build with 3mm aluminium the front was milled into 30mm massive aluminium´
Questions are welcome, I'll try to answer as good as possible.
I'm very happy with this two amps. I like them. Now its time for building a preamplifier.

That looks great, especially beautifull casing!
How do they sound?
What type(s) of wiring did you use?

Hi Raphael,
Amazing job! I really like the power supply PCB surrounding
the transformer.
Quick questions: Why two pairs of binding posts on the back?
Cheers,
Dennis

that is some great work!
i like the way you incorporated the look of the production
Aleph-X, but in your own style.
Submit your pictures to PassDiy, this amp needs to be in the Gallery! 🙂
...the only question i have is are you using fans
for the heatsinks? 'cause they look a little small.

Very Nice!
Very nice design work. I especially like your chassis and front plate. Did you cut the AL yourself? I'm just now in the starting phases of planning my chassis and your work is an inspiration!

Beautifull piece of work!
I'm very impressed by the casing. How did you do the 30mm front-panels?
btw, whats that strange looking component on your input stage... some magical mystery component?

Very nice indeed!
They recall the (new) PL trend, but without coping it, I like your look very much...

Yes I'll send some pictures and a a short description to PassDIY.com within the next few days.
Dr. Gone, what do you mean with wiring. The speaker cabel? They are T+A Speaker Six. Why I used it? It was lieing here so why not using it?
@Dennis: Because of Bi-Wiring. I'm using Monitor Black&White speaker cable, two binding post make it easier.
@moe29: I'm not using fans. I thought about it but decided not to use fans. But I can mount two fans per unit if it will be turned out that it is necessary. Therefore the two grills on the back side. but after running the amps for one hour the heatsink temperature increase stops at 53°C.
@Eric: Not really. The front panels were made on a CNC-machine. So, I had only to draw and to varnish them.
@dr. strangelove3: Yes, thats the ghost of Class-A. 😉

No, I meant internal wiring. I ask you this because I'm curious what type of cable people use inside their amplifiers. Since many people (I assume) use wiring outside their amplifier that may cost quite some money, what type of cable do they use inside their amplifiers. In my experience, cables can influence the sound quite a bit, but in the past few months I haven't read a single post (on the Pass Labs forum) about cabling inside the (Aleph) amplifiers, I was curious...
