Asking for help to build dc power supply for any audio amplifier......

That's a pretty tall order. Also nearly impossible. You have to have a range of amplifier requirements to start.
How much power?
Mono or stereo?
Speaker impedance?

Higher power amps need more mower form the power supply. Some amps need only a single polarity voltage while some need both
positive and negative voltages. Some amplifiers are more efficient than others. More efficient amplifiers need less power than less efficient amps.

Define more specifically what you need and then maybe someone can offer some help.

Cheers,

The requirements are as follow :

Power : 40 Watt
Speaker Impedance : 8 Ohm
Stereo
Loudness: 36 db
12 db Crossover
Transformer : 6-9-12
Range : All Current audio amplifiers coverage
Voltage: 110-230 volt
Regulated Voltage

Thats all for now !

Do you have any schematic of this power supply ? Can I see this ?

Have you worked out the requirements yet? - see my previous post - if you can't do simple secondary school maths you're going to struggle building anything.

Once you have, next do you want single supply or split-supply.
