Hello everybody, I wish I could increase the max. current from 3 AMPs to 5 AMPs e.g. by changing the transformer, diodes and Tran sisters and PCB tracks width and heat sink etc. Anyone with good suggestions? Alternatively, is there a good switch mode PS circuit with variable voltage and variable current limit that has max current 5 Amps or more? if you need you can join with me. This is a good help line for all of you. Thanks
