Greetings!
After my last post, Super Simple Class AB, i've decided to try the common approach for build amplifiers because of the inumerous illimitations that it provides. But i've some questions about stability of my amplifier and decided to spent some time over simulations.
I'm trying to find some errors or inconveniences...

So. Ive used multisim to simulate.
What i've got from this:
10W RMS @ 8 ohm 1Vpp input
THD 0,04% typ @ 100hz(About 0,037%)
THD 0,04% typ @ 1khz
THD 0,06% typ @ 10khz
2,5W dissipation on the power transistor
Other concern is that this amp, when deliver such potency, reachers 1,6A peak, and a stereo theorycally would push 3,2A from the power supply.
I've a transformer 12+12 @ 3A and idk if i can use it to this project because 2 amplifiers overload a little bit the specification. This can be compensated with a good bank of capacitors?
I'm open for suggestions guys!
