Why do you want a minimalistic amp?

I don't think you can leave out the mute and standby components. Both need a positive voltage on them I think and one has to rise faster than the other. Check the manual.
Cheers.

Hi, Al Bundy !

You for certain cannot leave out the st-by circuit.

Couple months ago I have built an amp with the 7293. You can see it here. There you can also find my PCB for download.

I know I posted this a litle bit late, but still hope this will help you.
