This is the bare PCBs of a stereo class A MOSFET power amplifier( a set of 2 pieces) , which features low noise linear J-FET input ( such as 2SJ74BL can be used), and single-ended MOSFET output for ultimate class A performance. This is a shorter board version of of our another item " MOSFET SE class A JFET input power amp stereo huge PCB" . The circuit is the same. The board is good for users who want for a more compact housing. We provide schematic to buyers by EMAIL. We do air shipping worldwide at US$5.00.
