Default Ta2020 ta2024 tk2050 Hiss hissing noise hum !@solve

wanted to try one of 5.1 6 channel ta2020.
notice some errors corrected all + mods for 2vrms input,and still hissing.
used feedback capacitors as in drawing,but volume decreased just a bit ,i guess formula not correct anymore( for clipping protection).
The hiss has been reduced with the feedback capacitors by much,no Noise when input not connected ,but still just a bit of hiss.How can i reduce that to have nice sound?did i do well with the caps?(apparently distortions reduced)
using 9.98-0-9.98 VAC transformer rectified using two diodes with center as Negative.
i just want it louder,how can i make the formula work with those caps in.
