Thanks for this helpful post. It looks like the OP's problem was fixed with a fuse replacement. I have not been so lucky.
My iFi is about two years old, and was left powered on at all times. I went away on a business trip for a week, and when I came back, it was dead. No light on the dock, no response to any control, no sound from a line-in signal.
I searched the forums, found this post, and got myself over to the Shack for appropriate fuses. I got a package of both 2A and 3.15A slo-blo fuses.
Took the subwoofer apart, checked the original fuse - blown. Inspected MOV1 - appears to be OK, no obvious problem. Disconnected the transformer primary connection and tried Check 1 with a new 2A fuse - no problem seen (fuse OK). Moved on to Check 2 - reconnected transformer primary, disconnected transformer secondary, and tested again. The 2A fuse blew immediately when power was switched on. I tried again with a 3.15A fuse, and got the same result - the fuse blew immediately when powered-on.
Just for grins I tried it again with the transformer secondary (and primary) connections in place - same results (fuse blew immediately, both 2A and 3.15A.) For whatever it's worth, the power supply filter caps physically appear to be OK - no bulging or obvious leaking.
So...what do I do now? Any help you could offer would be appreciated.
