Dual power supply regulated power supply output circuit diagram (solution) [Copy link]

The subject our teacher gave us is to design a low-frequency amplifier with 8-channel audio signal input, single-chip control switching, single-chip control gain, and intelligent signal amplification capability!
The power supply part requires a 220V50HZ input regulated power supply with dual power output, and the output does not exceed +-25V!
I can't draw such a circuit diagram. Please help me solve such a circuit diagram! Thank you! I am waiting for your response!
The attachment below contains my design circuit requirements!

It is impossible for me to make all the circuits for you. You can do it first. After you are done, I will give you some suggestions on the circuits and check them.

Please tell me the power supply specifications and parameters.

The teacher gave us the things in the attachment for us to do. Look at the things in the attachment I sent. There are design requirements. We don’t know where to start! Please teach me!

You only need positive and negative 24 volts, and do you have +5v? That would be easy to do.
