Hello, I plugged my 120VAC made-for-USA Denon DN-600F CD player into a 220VAC power outlet, and the CD player won't work now. I looked inside to see if there was a fuse I could replace...but there was no fuse; so it must be that the high voltage damaged the power supply transformer inside. I would like to try to replace the transformer myself...either by getting it rewound, or by finding another transformer with similar specifications. Could anyone help me, and tell me what the specifications to that transformer are ? There's nothing much written on the transformer or the circuit board that I can understand......it just says .66 on the transformer, and maybe another number with no indication to what the number describes. I would be grateful for any advice - anything I need to know to undertake this repair. Thank you.
Hello there. i'll suggest you one quick solution but it maybe dangerous!(Do it the greek way :P) try to remove the transformer from the machine. Take one Ohm meter and measure the resistance of the 120 vac coil. IF THERE IS NOT ANY (i mean that the ohm meter shows nothing diferent than not using it) get a paper blade and start removing the paper cover that it has rounded from the place where the 120 vac wires goes. you will see there that there is a mini thermal fuse.short circuit the thermal fuse and try to measure again the resistance of the 120 vac coil. if you see something between 40 and 80 ohms you are ok. Now that you haven't got any thermal fuse on your transformer just increase your security putting on a 300 mA fuse at the 120vac coil. I have done it with many hard to find transformers and it worked for me.Just be sure that when you plug it on, you will not touch it because i don't know if you are gonna do it right.ok? (say ok!) That was the second solution to your problem. The first and the safest is to go to your local dealer and order a new transformer.
