I have built the circuit shown below (audio amplifier using lm386). Replaced the chip today after i had destroyed the last one due to stupidly supplying wrong voltage polarities. I also added a diode to protect it, but as i connected it the chip gets hot aswell theres was smoke that came from the diode. 12v.
Is there an easy test circuit i can use to determin if me ic has blown again?
Anyone might think of the problem?
