WebAfter reading everything about voltages, and Thévenin's equivalent circuit, I'm in the chapter about "MOSFETs." Those MOSFETs are supposedly separated in two versions: switches, and amplifiers. I know what PNP and NPN transistor are, and I know where to buy those things, but I found no place on the internet where I could buy those strange MOSFETs. WebFor an amp with +/- 50V Vcc rails, get a MOSFET with more than 100V, preferably more than 120V Vdsmax. Also, since current rating is cheap in MOSFETs, get devices that ensure that there is enough current handling capability to not "choke" the output stage of the amp. If necessary, you may freely parallel MOSFETs to get more current capability. highest mountain in our solar system
