Today the Chip arrived, but found that it was the wrong type, this was the numberEM11G LM3B6N-1 . But tried it anyway, is it normal that the loudspeaker came out a lot of noise at 9 volts . No display light or anything else . If I have the right chip running then everything normal ? display sound, volume bands ect..... Thanks for the remote help
