Hello karma,
the heatsinks are very expensive (high power heatsinks), but really good. You have to count about 90-100 Euro per heatsink

The Aleph works with 47V secondary and I measure 48°C at the heatsink. The confection is very good.

Hello Trigon,
it is an inrush protection, and an NF-switch. An incomming signal switch the amp on, in the first step over an 25W resistor which will bridged after about two seconds. After an definitive time without incomming signal the electronic switch the amp off.
It works fine
Re: yes
I used 10mm Alu-Plates. The heatsinks are 200X300X80mm big.
The high of 300mm makes a very good convection.
My aleph works with +- 47V and the temperature at the heatsink is 48°C.
I got the heatsinks from http://www.fischerelektronik.de/_2002/PDF/Einzel_PDF/A_44.pdf

Nice Job, Did you cut the Aluminimum Plates
I've been looking for a better method to cut Aluminum plates. Look to me like you found it. I've been using a bandsaw, however a lot of clean up is need after cutting. I was thinking about cleaning the up edges with a big belt sander, however aluminum will wear it out fast. Any suggestion
The bevel edges look really nice.
Thanks
JW

Re: Nice Job, Did you cut the Aluminimum Plates
the aluminum plates were sawed with a belt saw and milled following on a milling machine and chamfered 45°.
With a circular saw you will see better surfaces as with a belt saw, however optimally is only a milled surface. Sharpen Aluminium, to get better surfaces is very difficult.
Sorry, but I don´t have a bette idea.
Maybe you have to ask Peter Daniel, his Alu-works/chassis are looking really nice.

Hello grataku,
you are right, the panels are anodized Alu-nature.
The power switch I bought by Conrad http://www.conrad.de/scripts/wgate/...late=PCAT_AREA_S_BROWSE&shop=B2C&p_init_ipc=X
it is a Carlingswitch Midi "Visi Rocker".
The fast rectifier diodes are getting really hot, about 80°C. I think it´s behind the limit.
