In this video we will be having a look at my previous simplest audio amp that was made for wired headphones. It is a Class A amp that now needs a boost in power to drive a loudspeaker. I will show you how to do that and also try to use a MOSFET as a "better" audio amp. Will it be better though? Let's find out ;-)
