Is a very good idea!

Yes, Pavel Dudek has introduced this mechanical design 20 years ago.

Yes PMA, Yes, you are right, but Bohumi Federmann has introduced this mechanical design 38 years ago
Where Mr. Federmann? Please show
Your first post. Veli good. The thread is something else.
What´s wrong with your last revolutionary design, cooling with case? http://www.diyaudio.com/forums/vend...mp-5-pairs-irfp240-9240-a-12.html#post2655262
Why did you use ancient vertical heating profile? The cooper bars Pavel Dudek introduced, like PMA writes.

I named the mechanical structure of HM/AAA or Heavy Metal Analog Audio Amplifier
HM/AAA aneb Heavy Metal Audio Analog Amplifier
All wiring is very easy ...
Paul very nice work, but very many connections, and little cooling.

Really, Federmann? This amp gives 120W/ch and heatsink is 130x300x40 mm, while yours gives 500W/ch (how you declare) and heatsink is 150x400x40 mm...Which one of these has larger area for this nominal power dissipation? And connection: I am using for output 120W 2x2 16A WAGO, TWO IN PARALLEL, while you for 500W only 2x1pin, which have only 12A...What do you mean, which one connection will have higher reliability ?

Many, connections? Input, output, power supply and that´s all. It´s more connections on this picturePaul very nice work, but very many connections, and little cooling.
Little cooling? No, it´s only larger PCB than yours Bohumil.

What is more?
Heatsink 120x400x40mm + Cover 360x360x6mm + panel 360x100x10mm vs. Heatsink 130x300x40mm
I have any problems with cooling of this amp and many users too, Federmann...is funny, if you argue with cooling of bottom and upper cover, 'cos there is air circulation minimal and exchange of the heat into air will be only symbolic, particularly if you give him into the rack...
BTW, efficiency of cooling by these parts was demonstrate by your prototype of this amp, which was without heatsinks...

Federman, how I see, your electronic hobby lead to prenatal age......all you know, all is your design..hard to debate with you, I don't like your brainstorming...
Upupa: You do not agree with me, especially when you do not understand.
