Re: U1 fried
I assume the mono to serial adapter would just short the mono signal to both stereo signals.toggle quoted messageShow quoted text
So you are back where you started, plugging a mono jack into that adapter will kill the TDA2822M.
Could work if you avoid this, but not foolproof. And thus not suitable if I'm anywhere in the vicinity.
Might be better to add a series resistor inside the radio, and/or reduce the supply voltage to the TDA2822M
