first of all thanks to everyone who helped me with my last project it worked ![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Now, I'm building a 22W amplifier.. to be particular this amplifier: 22 Watt Audio Amplifier
The amplifier is not that big of a problem, I have all the parts i need and i will be just simply screwing the chip to a metal box(yes the box in which the circuit will be in, not a good idea?) and then to be safe I'll put an extra fan on the top of the box to make the chip cool.
Now, I want to build a power supply. Now I'm from Europe so I need to convert 220 AC to 12V DC. This is a problem.. I think I found a right transformer for the job.. a 25VA 220/12V Toroidal transformer. This is the only one that i found that would support the power of the amplifier. I would build the power supply according to this schematic: https://www.circuitstoday.com/wp-content/uploads/2009/05/simple-ups-circuit.jpg
Is that good?
Thanks a lot guys
