You can not believe how expensive housings can be!
Since I absolutely wanted to build a complete power amplifier, which is not like some other manufacturers usual, with a separate power supply, I had to build my own housing.
On the left PA ventilation, cooling fin, 10mm copper plate and
shell PA module.
On the right, the built-in switching power supply with the three fans.
View from the rear, the ventilation duct of the PA module can be seen on the right.
Front view, on/off switch, touchscreen display and below a
perforated plate for the
the sucked air. Here you have to consider which perforation
distance is useful to achieve an air throughput that is sufficient.
View from the rear, still without holes and openings.
This was the shell, the housing fit together and so then could
drilled and then the aluminum was brushed and anodized black.
And here is the finished case, this is how I imagined it....
