Yes. Don't ask schematic again. My boss will punish me if I disclose it. I don't want to lose my job. One thing is that it is new. In this thread I only want to show a new kit. It is danger for DIY.

Another thing is my studio isn't underground. It is in 10th floor and very sunshiny.

What is the outputpower in 4 ohm?

Just a little schema?

Yes, it is slim. A fan cooling is needful in system design. The temperature is 45¡æ with fan cooling. Circumstance is 20¡æ.
