You purchased a japanese domestic model. Very few people imports those because of the reduced FM bandwidth and weird 9khz tuning steps on AM. And there is no 1:1 equivalent form Japanese to non-japanese models, so your chances of finding that transformer and PCB is slim. Your best bet is to rehabilitate that PS and transformer. There's nothing really special about transformers, it just steps down AC to the power requirements of your boombox. Just get a new transformer that is suitable in terms of size and voltage and mounting style, and on the PCB, just replace any electrolytic capacitors (they abhor over voltage conditions) and replace the bridge rectifier or diodes. Then you'll have a regionally correct AC capable boombox. Alternatively, you might have better luck trying to source a similar regional variant. Maybe the RX-DT75? Just be mindful that if you haven't yet checked to see if the boombox itself is damaged, you might discover after going through a lot of trouble that the PS is just the beginning of your problems.
