I purchased a used Bazooka amplified bass tube a little over a year ago. It has worked well up until yesterday. Yesterday I noticed that I had no bass and the LED on the amplifier was off. I checked for power at the power cables to the tube with a multimeter and there was power. I then took off the fuse located ON the built in amplifier and found that I also had 12 volts there. I checked the remote turnon and everything was in order there also. My best guess is that the amplifier is blown but I was hoping someone could help me out and tell me if there are any other things that could cause this loss of power. Since I purchased the tube USED I don't think I'll be able to send it in for warranty repair either, and to be completely honest it's not worth 60 buvks plus shipping to get it fixed, I'd rather spend 150-200 bucks and get a used amp and 2 12 inch subs in a box. However if there are any things I can do to check/repair the problem I would like to do that.
