Does your mains power supply socket/plug have a third pin to protect the users from equipment faults?

 

[dannyjmf]

currently not yet .... but planning forward to do it later .... this is still under prototype ...

another surprise i found ..... though i didn't really build a power supply with high capacitance value .... also using strip boards for these amps .... noise is almost inaudible ....

The LM1875 has 94dB ripple rejection. I should HOPE your amp is low noise.
