This MOSFET amplifier is designed to be as flexible as possible, with no bad habits. Indeed, it will operate stably with supply voltages as low as +/-5V (completely pointless, but interesting), all the way to the absolute maximum supply voltage of ±70V. The only change that is needed is to trim the MOSFET bias pot!
