I want to build this simple audio amplifier and I need some information from you...
1)Are all the resistors 1/4W? What about R11?
2)What should be the loud speaker? will a 20W 4-8 Ohm works? and what's a best choice?
3)Is there any IC that outputs +20V 0V -20V from a 12V battery source and if available, handles the required power for the circuit? Any other idea how to feed this circuit from a 12V battery source?
Thanks
