21W Class AB amplifier by TIP41

This is an instrument amplifier for monitoring music when on stage. It provides 21W output power of this little design. Previously I had a decent 10W amplifier (RED Free Circuits), but we blew that one somehow. Now I will put this into the old box. I haven’t built it yet, but the simulations say it works as I designed. In this design, wiring is important due to no differential amplifier. I might need to add ripple rejection with a zener as in the above design.
