Does anyone have any experience w the old Nuforce Ref9’s. One of my amps seems like it’s shot. Blows fuses on turn on. I talked w Bob smith on the phone and he said it’s almost certainly the power supply. It’s a switching supply. Seems pretty generic. Would getting one off eBay or another general web source be a bad idea? And I’d assume I should replace both so the amps sound the same and have the same power. I’d send them to bob I just don’t have more than a grand to throw at these. And. I only have beginner electrical experience (I haven’t done anything harder than recap a pair of speakers).
Any commentary would be appreciated. Thanks

If it's a bad power supply, swapping in the good supply from the other amp
should make the bad amp work.
should make the bad amp work.
I’ll try that to test it. But as I now only have one amp, my question is trying to get at: Are these switching supplies interchangeable if the voltage is right ?? How hard are they to swap out?
Modular SMPS just have connections for the input and output.
The physical shape and size may be a problem with substitutions.
The original is almost certainly a custom, purpose-built design that will
be difficult to replace both electrically and mechanically at the same time.
The original could also have special features not in generic supplies.
I would ask Smith, he may be the only one who really knows.
Otherwise, try anatech, a moderator here, there's a chance he might have
worked on these. He could possibly repair a bad supply for a reasonable cost.
