i decreased the voltage to 5 volts and the problem with the heat went away, i replaced the 10k resistor in the schematic with a 10k pot connected similarly to the 10k gain adjust pot in the 386 data sheet, and the problem with not enough gain went away. i also found the source of all the noise in the circuit, it was not caused by RF or feedback, it was caused by the 2 fans sharing part of the circuit (they did the same thing to the 386 amplifier i made). the problem is that when i build my circuits, i usual build them i bulk so there tend to be some power issues. witch is why i want to make my own high current power supplies. the problem is that everyone left me hanging on my post. they said that a 4.7mF capacitor was too small for the power supply, and they never told me how large i should make it, or how to calculate the size.
