Hi,
Don't think I am a DIY person because I am a member here 🙂 I can do "some" stuff but not too much 🙂

So, I bought this DAC from someone knowing it was not powering up. The seller said he had no time to check and I took my chances thinking it could be an easy fix such as a bad fuse. I was like you know what I had a unit with an issue before and a fuse replacement solved the problem. Maybe this will be the same.

I put the appropriate fuse I hope because that's what it had in it, slow blow 3/8A (375mA).

WELL, THE UNIT POWERED UP, I pushed the buttons, they were all working, etc. two minutes later, I saw the fuse burned like red and then puff! The unit back to dead again 🙂

What could be the reason for working few minutes and then burn a fuse?

I have a friend who has all the tools to fix it (if fixable) but I thought let me ask here maybe it would help him pinpoint the problem.

Maybe I did see tiny caps touching the part/metal next to it and I did move them little bit so no touching, did a contact cleaner session 🙂 but still burned the second fuse AND actually last night I didn’t notice, but today I plugged the unit and didn’t even turn it on and the kind of loud buzz noise and then burned the fuse. I have a video of it too. Here is the video:




Here are the photos of the inside. As you see, looks pretty good in there.
