This is the first video i see that makes sense and obviously made by someone who really understands the circuit

EXCELLENT PRESENTATION!I WAS JUST WONDERING HOW DO YOU MATCH TRANSISITORS SO THAT THIS WORKS PROPERLY?

I have a question. When you say that the collector current Ic is in saturation, does that mean that the transistor itself is in saturation region? That kind of confuses me , because every book I've read said that for an amplifier to work properly the transistor must always be in the active region of operation.

Hi Mr. Professor Fiore<br><br>Are there any possibility of having both transistor (NPN & PNP) conducting at the same time?<br>Thanks

Just as good this time around. What would a typical audio amplifier (power amp) voltage compliance be, please? I can see the V2/R squaring up and a couple of extra volts can make a huge power difference.

Thanks for another great explanation. With respect to the AC signal between the diodes: Is it the case that the small current flowing into the diodes node reduces the current flowing down through the top diode but the diode is always on so the current increase/reduction allows the signal to pass through? This hasn't quite clicked although it makes sense. Thanks in advance. It's the thought that something can go backwards up a one-way street where it's really just slowing down and speeding up but always travelling in the right direction. (That was me thinking out loud, is that right?).
