    Hi there—long time watcher, first time poster. I am sure what I am about to ask has a specific older thread, but I didn’t see what I was looking for.

    I have a (new to me) used D800 into a used subway 12”. When left on for more than 10 mins, the amp starts to put out a louder hiss/hum. If I shut it off, then it is fine again.

    I have tried a new power cord, and power strip. I have not tried a power conditioner.

    Any thoughts? Fan? Something ground or thermal?

    Thanks for the help—Jeff

    @agedhorse will chime in soon, but the best thing to do would be to contact Mesa customer support. If you can get the original receipt, it may still be under warranty.

    You should call Mesa customer service.

    just curious if anyone has had a similar issue. This is out of warranty, so I would mostly likely try some other fixes before shelling out more on something I just spent money to get

    I doubt that the 5 year warranty has expired!

    I guess I will check the date it was made, I was unaware it was a 5 year warranty. I assumed it was less, and this has to be at least 3-5 already. Thanks.
     
  7. It has a Five Year Transferable Warranty so you should be covered if needed.

    Welcome to TalkBass, the man that designed that amp will be around soon.

    D-800 was released in Dec of 2015. You're still under warranty.

    Is the noise a hiss or a hum? This is important information.

    Customer service will be able to help, the shop is closed Fridays, open Mon-Thurs.
