In reply to Asif. i think you can use touch switch circuit, please try to find in another post. just leave the stanby and mute system as is without connection (NC).

I built this amplifier today, this is a great, yes I said great power amplifier to be made by a beginner. I?m really impressed by it?s clean-ness of sound, and also, the bass is really perfect?.

I just have some questions, how can I wire mute and standby switches? What kind of switch is good for it? Like a switch when we press it and it stay on, or the other switch when we press it, it does connect and when we remove our hand from the switch it disconnects?!!!

And I?ve another question. How can I permanently remove those standby and mute system from the circuit?
