I'm looking for someone who is expert in PCB Design especially in Analog Audio circuit It's a simple circuit -Through hole converts to SMD -Reducing the noise of the circuit -KiCAD to Eagle I need someone professional who can improve the design I will provide you more details

Adapt PCB from Eagle to KiCAD and increase performance from current 80A to 200A with peaks of 400A (specify heatsink for the design). Theoretically, used MOSFETs (FDMT80080DC, two in parallel) should be capable to handle 200A requested currents if they are cooled properly, but heatsink must be calculated. Also the Würth press-fit elements are already capable to handle 200A in theory. Probabl...
