None of these simple designs will be capable of the required power output. By nature, you will need a much more complex design to accomplish this with even moderate efficiency.
is the best !! is out high power !! my home amp is work !!! very good!! ( my amp need 340W ) and can turn on 5- 100W lamps !!!... and it conect to a big transformer...
This circuit is unregulated. It wont work for audio. Your rails will be low. This type of circuit is used in applications where a constant power consumption is needed. Audio has varying power demands and a regualted power supply is needed.
