This is a class A , 5W( at working voltage of +19Vdc) single ended MOSFET power amplifier PCB. The circuit consists of a current source loaded, single-ended output mosfet with J-FET input. The circuit is simple with beautiful sound.
The amplifier has a mellow damping factor resembling most of the SE tube amplifiers and is very good for high efficiency speakers.
We provide schematic and part list to buyers by EMAIL.
