Nice looking design. Do you need to have the vents up front? Venting out the sides between the heatsinks lends itself to better cooling, will clean up the front and lower your manufacturing costs.
No Mr.Nelson , I don't know the BGW products , but thank you for information.
I like very much huge Vu-Metter with many LED and I saw in a movie a broadcast console with a similar Vu-metter.
I don't know why in our days, people ( or manufacturer , perhaps ) do not like to have any type off controll for their amplifiers.
For Philo ,
Yes I need the vent up front becouse I want to use this design for pro use (cooled by a fan) and the amplifier it would be inserted in a 19" rack.
Thank you for answeres !

Very Identical to the 750B
It looks almost exactly like a BGW 750B. The front light arches on the early 750's were all red until midway through 1980, when BGW figured that multicoloured would be better. About the only difference in your amp and the 750B is the gain control knobs on yours are to the side (where the 750B's are underneath the meters) and yours has front cooling vents; and the BGW does not.
I think that the front vents would be good to have on the amp. The design of the BGW has slots that are cut out on the left and right sides of the top cover. The cover only covers the output modules. But actually the top part of the output module is just a heat sink, and the the whole thing mounts on to the top of the chassis. The cover just goes over the modules to act as a directional flow resistor to the outside air comming in. By this I mean, the cover is slotted on the left and right sides (where it covers the side of the modules). There is one single large fan in this amp which draws air from the inside out. The cool air from the outside comes in the slots and travelles along the heat sink to the center when it is sucked through the space between the modules and then exits through the "pusher" fan on the rear panel.
Its actually a great design. In your case, having the vent slots on the faceplate of the amp will be better if the amp is going to be housed in a "tight" rack. -I mean tight with space and air. You could even think about adding a 2nd small fan behind the front panel which could draw the air through the slots and force it into the amp. Then position your output heatsinks (if it is a module design) close to the pathway of the airflow from the front fan, and then to the center of the amp where it could be exhausted through the rear. I have a Renkus Heinz p1500 amp that utilizes almost this same design. But the Renkus Heinz has each channel output secluded on either side of the chassis with a separate fan for each channel. The fans on that amp are real monsters too. Another remarkable cooling design.
The best heat transfer will take place when the amp chassis itself acts as an adibatic system with transfer only from the system as a whole.
