DC All FET Cascode class A amplifier PCB and 50 similar items

This is the PCBs of an ALL FET class A amplifier. The design is with reference to Boberly 2 stages cascode circuit EB1198/116 to form an ultra low distortion and high speed amplifying and driving circuit. The final stage is a pair of lateral MOSFET as to get to a 10w class A operation. When appropriately implemented, the amplifier can perform a open loop gain of 66dB and distortion of 0.05% (1kHz, open loop !!) and below 0.002% with mild feedback ! While the default circuit uses power MOSFET on the output stage, the design is universal and not confined to be used only as class A power amplifier. For example, medium power MOSFET can be used instead to form a high current preamplifier or headphone amplifier. With small signal transistors drop in place, the design can also be used as a high speed buffer or line amplifier for active filtering and other amplification purpose.
