I have an Icom FR-4000-3 that's emitting a high pitch sound from the PA. I try to ignore it but it's there. I checked the PA and all the capacitors look good. But I was not able to test the readouts due to time. Everything is working as it should. I have uploaded a video on YouTube to see what you guys think it is and to see if this is normal. Your time is appreciated.

Hello Everyone.
I have an Icom FR-4000-3 that's emitting a high pitch sound from the PA. I try to ignore it but it's there. I checked the PA and all the capacitors look good. But I was not able to test the readouts due to time. Everything is working as it should. I have uploaded a video on YouTube to see what you guys think it is and to see if this is normal. Your time is appreciated.
