MHDT Paradesea Repair? New Tube?

I have a MHDT Paradesea+ DAC. I stopped working the other day. I tried another DAC and it worked fine. When i plug in the Paradesea i can hear a VERY faint sounds coming out of the speakers. I tried going USB, coax...no go. Could it be the tube died? If not, does anybody repair these things? Is it worth it?

First thing, replace the tube with another which seems quite likely based on what you are hearing. Tubes can get noisy over time. I do believe the Paradesea uses the same buffer tube as the Havana 5670, 2C51, 396A type.

is there a wary to test a tube? Should i just buy a really cheap tube to see if it works first?

The ideal is to find a tube that has been reliably tested. You shouldn't have to spend too much for one of the above tubes.

If you post your location, there might be a member nearby w a tester. I'm in the Hartford CT area and might be able to help if you are near there.

Most likely the 5670 tube. Always good to have a spare to test with when needed.

paradisea sound changes radically with different tubes so tube rolling with paradisea is a worthwhile exercise in of itself.
