I have a Jensen Surround Sound System that has developed a very loud hum coming from the subwoofer. I thought it may be a ground problem but it continues to hum when there is nothing connected to it except the power cord. Should I chunk it and start over?!

Sounds like you have a problem with the ground. Check your connections to the power supply and your outlet. Then again, your other problem is, it's a Jensen.

Sounds like a bad power supply in the sub. Chuck time. Perhaps salvage the woofer.


Enjoy.

I know enough about this stuff to get in plugged in and that is about it!

I just hooked up my new DD-15 and all is well again, however I'm trying to figure out what to do with my old F-1800RII. It served me well for years before developing an incurable hum (along with random pops and distortions) and I have no idea what I'm going to do with this huge (beautiful) box and 18 inch driver.


Assuming it is the power supply, is there any way I can fix it? I emailed Velodyne tech support a while back and didn't hear anything.


TIA for any advice.

Go on the Velodyne support thread and post your question. I am certain that either Bruce or Curt will be able to help you. Good luck!

Try to float the ground from the power plug by using the 3-prong to 2-prong adapter

well if its no good chuck it and then hook up the sub directly to the AC and watch it smoke!!!!!! Its always fun to watch a transducer Launch from too much power.

Thats a band-aid approach and I personally don't recommend it. Try getting it fix first.

Even considering the cost of having it serviced, I certainly wouldn't consider it's worth to be reduced to that of the box & driver.
