Hello,
as mentioned in the title, i bought a LM1875 as i wanted to build an audio Amplifier. I first built the "standart" circuit ive read on the datasheet, on the breadboard. As everything worked fine, i welded it on stripboard but it didnt work anymore: the speaker begun the hum, the ic immediately got hot as soon i plugged in the power supply, all this even with no audio input.
its worth mentioning that i tried to rebuilt the circuit multiple times, to check, double-check and triple-check if every connection was right and to rebuilt it on breadboard thinking the ic might have passed out resulting in the circuit working again!
Does someone have a clue on what could be the problem?
