Sure.
Take some pictures from net and tomorrow i will post more pics about my amp.
Thanks a lot.

An externally hosted image should be here but it was not working when we last tested it.

Most amps that use this basic design (from that I can tell from the limited resolution) have unregulated power supplies. If you have a variable voltage power supply. Measure the DC voltage with the black probe on leg 3 of the power supply FET and the red probe on leg 1 of the power supply FET. If the voltage decreases when you reduce the voltage, the supply is likely unregulated. If the voltage goes up when the DC input voltage is decreased, it's likely regulated.
If it's unregulated, the only way to increase the voltage is to add turns to the secondary windings of the transformer. You should be aware that this is likely to make the amp run hotter and will likely make it less reliable if it's driven to full power for more than a few minutes at a time.
