I have a functional TDA2030 PCB that I made right from the datasheet but it clips with minimal input. I am using a 12.5-0-12.5 2 amp transformer and a pair of 4700uf caps in the power supply. Here is the preamp schematic that I am currently using.
I am only using it up to the volume pot with out the extra gain stage on the breadboard. LTSpice says that I should only have about a 400-600mv output after the BM tonestack but I can readily make the power amp distort.
Will this lead to premature failure of the power amp chip?? From what I get out of the datasheet I should be able to get closer to 890mv input to get the maximum power output.
