A power MOSFET is biased using a pot (needed to correct for different device characteristics) so that the voltage at the drain is about 1/2 the supply voltage. Current is limited using a constant current source, and this needs to be set to provide a current that is higher than the maximum peak current to [...]
This is simple Class-A MOSFET Amplifier, used mosfet 2SK1058 in circuit.
It is easy to make, Must use supply volte 24V at high current. read more

I am using this Class A Amplifier with a 12AU7 based valve preamp. It produces the most purest sound. I have no idea of distortion levels etc. but it has [...]
I was in need of high quality headphones amplifier because of many reasons and decided to build SDS Labs phone amp. This is extremely rewarding project in a sense that it is fully documented, includes PCB, parts list and building notes - so it’s easy to build and then it sounds great. I have used [...]
