MHDT Paradesea Repair? New Tube?

Sounds like fun. Good to see you guys all on here after so long of an absence. I remember you guys when I was into this in the early 2000s .i've got little kids now so there's always a possibility to that they spilled something into it that's why I'm a little nervous. Maybe if you guys have a tester I can mail this one to you and just tell me if it's good or bad before I buy a $75 tube!

Why would you sweat a 75.00 tube? Even if it's not the problem, if you keep the DAC you will eventually need to replace it.

BTW, have owned the Havana for ~3.5 yrs. and have replaced the tube once already. It is an excellent sounding DAC.

I'll check to see if I have settings for the tube and will pm if I do.

The problem with a noisy tube is that it may test well but still be noisy. I have a Hickock tube tester. While it performs several important tests it doesn't test for noise. Buying from a reliable tube vendor, Andy of Vintage Tube Services immediately comes to mind, is a good way to go if you call him and talk to him and tell him what's going on. In addition to being a tube merchant he is extremely knowledgable in general and can possibly give you greater insight into other possible causes and the MOST probable cause. If you are on a budget and just want to get the unit up and running the FIRST thing I would do is to buy a CHEAP reliably tested tube from a guy like Andy to see if it IS the tube. After the problem is resolved THEN you can consider different tubes which DO make a difference in the MHDT DACs. Hope this helps you going forward.

Ok, called Andy at tube services. He said if the tube is fully lighting up it's not the tube. So, i took it up and sure enough the tube is lighting up. Looks like it is something else. Will look into either repairing it or replacing. Thanks for the info guys!
