Sajid, VA3QY asked Ashhar Farhan where he could source a new and reliable TDA2822 audio chip.
Ashhar Farhan has replied, “I am working on an audio amp. I am testing it live. I always personally use circuits on the air before recommending them. I hope that by Tuesday I will have something you can use. About 100 out of 4000 boards have had this problem. and less than 20 of them have reported the blow out.”
