Sony Walkman WM-FX425 power supply

Hey Everyone, I have a Sony WM-FX425 Walkman and want to chase up a power supply to avoid using batteries. The manual isn't telling me much other than it runs on DC 3V. How much would be the minimum ma or amps I would need?

 

I looked up your user manual:

Theres 1 or 2 originals on ebay now.....

 

I am using this one, the AC-ES305. It works fine across most of the models from this lineup like FX425, FX415, FX407, FX315, FX101, etc.

I have an early model from this lineup, the FX19, it has a different plug size and inverted polarity.

P.S. I know the images are huge, but this forum scales images according to window size, so should not be a problem.
