The power supply board (AH41-00411A) on a RIO EX1000 that I've acquired is dead (lightning). I repaired it the first time, but then another power surge did even more damage (the previous owner had disabled the fast-acting fuse circuit which I did not have a chance to replace). Does anyone know where I can find a replacement power supply board? New or used would be fine. Heck, even a schematic would help! It's a pretty good music player so I hate to just trash it. Thanks in advance. Bob
Hello,
I don't have any solution for your problem BUT you can resolve mine : what color are the rings of the AR51 component (next to the big dissipator)

Hello, Guest!
Thanks for writing! I would love to help you with your problem, but I cannot locate the component that you referenced. There does not appear to be any such "AR51" on the power supply board (mine is Rev 3). In fact, there are no "AR" components at all. Most of the resistors are designated as "RR," and I couldn't find anything with a "51." Can you be more specific as to where it's located?
Also, if you have the same unit and power supply board, would you be able to provide me with the resistance values (color banding) for RR3 and RR4 (they are what needs to be replaced on my board). Both are located directly behind the two large capacitors, next to the a large transistor heatsink.
If nothing else, perhaps we can both help each other! Thanks again!
Regards,
Bob
In circuit value of RR3 .22 ohms. RR4 is .002. Colors, RR3 is Red,Red,Blk,Slvr RR4 is red,red,gold,gold . I took pictures so email me if you want them. [email protected]
