teeny micro-minature SMD fuses

Solder a bridge and see if the thing still works. Alternatively solder a couple of wires to the fuse ends and then to any fuse or fuse holder that you have handy. You can use an Ammeter to see what the current draw is and use a fuse that is rather for a couple of amps more.

Given the position, it does sound like a fuse, or a fusible resistor. But the markings are usually pretty vague on such components, so I suspect that a more informed search might bring up better replacements than the $1000 one you found. They won't be designed to be replaced, though with a special soldering iron, or some solder wick and some patience, it would be do-able.

I agree with Clocky though, in a DDS tape drive you should be able to find space to put in a normal fuse and connect it via wires. Then the question is whether there's a short elsewhere that caused the original fuse to blow.

Yep its an excellent way to see where the smoke comes out.

Best to start with a low current fast blow fuse, otherwise you may just as well solder in a short.

Which DDS drive? Model???

I got a used drive for $100, actually an old server that happened to have a drive in it. So got a SCSI cable as well, but the rest of the server is pretty much junk.
