As I understand it MOSFETs are transistors that a mostly used for switching, and with good reason. I have seen kits that use MOSFETs in a linear mode, I'm sure it won't be too hard to find some designs on the internet.

I have a small request (:

Could you please re-upload your electronics videos? They were great but they are of no use if no one can view them.

Excellent tutorial, thanks!

Thanks! My question is: how to get power Mosfets (useful for audio) in a linear mode, so that they can be used as linear audio loudspeaker amp. I dont have much experience with that issue in relation to power Mosfets (know the principles of bipolar types and can apply them). Do Mosfets also have a linear and a non linear part in their characteristic? And how to set them to these parts? What is the relation to their treshold voltage (if they have that...).
