I'm a student that inherited a Cobalt Qube 2 (server appliance) that I
run linux on and use it to store MP3s and test PHP code.
Unfortunately, I've determined the power brick has died. I cracked
open the brick and was able to was able to measure the correct VAC and
Amp for the input but the output end was completely dead. The output
should be 12VDC, 3.3A. In reality, I'd just buy a replacement but it
has a 3-pin round plug into the appliance and since the device was
EOLed ~5 years ago, I can't seem to find a replacement. Does anyone
know an individual or company that could repair this and approximately
how much it would cost?

Thanks for any help!
