Hi i have a broblem with my car amplifier project.
I use l15d board based on irs2092 and amplifier starts to oscillate when load is disconected and resistor in the zobel link start to burn.
The problem is only when amp conected to smps,when he conected to ac transformer ther is no broblems.
Does someone have any ideas.
