The Chinfa KAM3005 is a AC - DC Module takes anything for 85V to 240V AC and converts it to 5VDC to feed the digital circuits in the AA players. Its no longer available but there are several suitable replacement modules available. Thy are however not plug and play, they need to be relocated to in front of the power supply card then hardwired back to the card.
At the same time it is a good idea to properly heat sink the TO220 regulators etc on the Power supply card as it shows the run too hot.
Best of luck
