I'm encountering a tremendous difference in audio ouput between an s3 signal and an S9+10 signal. It's enough to hurt my eardrums !! Would reducing the value of R20 from 1 KOhm to about 680 Ohms give an increase in AGC action??? If I do this, is there any interaction I might inadvertently be causing??
