Class A Amp mkII

00:53:34

Working, with an output of 364 mw into 18 ohm (which is the claimed resistance of my headphones) . Hoping to get a little more if I can.

There's a slight flattening to the top of the output signal which I can't seem to get rid of. It's progressive, and all the simulations of amps I've looked at seem to have similar issues, but I'd like to loose it if I can.

Okay, that's better, but for greater thermal stability i recommend you put the 300ohm resistor from collector to base, and readjust it to 160ohm. Furthermore 1F is an enormous amount of capacitance, 1000uF will work just fine
