No. That is most likely part of the circuit that limits the current on the input side. The limit is there because the transformer has been designed down to a price and will saturate only just above whatever input current is needed to get 1 A out. So if you increase the current, you will just get the transformer saturating, and it won't be transferring any more power, but everything will get a lot hotter.I see the resistor in the AC side. If I replace it with a smaller one, would it give more current to DC side?
