    I was plying a show last night with my lh1000 and all was going well. But then out of nowhere it shut down. I didn't hear a pop or anything but it still could have popped without me knowing. I've looked into what it could be but I don't know how to tell if the tube is blown or if it's something else.

    Can anybody help me out at all?

    I would Start with the Tube and Fuse(s).
    The top comes off really easy(Just remove all the top screws) and the tube is "Locked" in by a spring loaded metal cover in the lower left Quadrant.

    I know this may come off as stupid, but my LH500 did that to me in the middle of a set and after going all thru the amp, cables etc. it was a battery dying in my active bass. Just sayin.

    One quick check. Can you get it to work when plugging into the effects return ? You can push down and turn the Tube cover anti-clockwise to pop the tube out and inspect. Best to have an extra one to test with.

    Can't go by the "look" of a fuse alone. Use a meter to test it's resistance (amp unplugged of course).

    Supposed to be a Fuse "Sled" at the power cord input.

    Now the question is why did it blow.

    Would a loose cable by any chance cause a blow. If the power wasn't plugged in all the way?

    I think that's what happened that was the first time I didn't make 100% sure that supply was in all the way I won't be doing it again anytime soon either

    It'll either be cool from here on out or may be have an underlying cause. It's just a wait & see deal. Good luck. I hope it was just a freak thing. I've certainly seen it a ton of times before.

    Now I have a new problem some wires and a resistor are getting red hot and the big power conductor or converter or whatever it is, is completely loose and has been like that since I bought the amp. I never really knew what was moving around and I thought it was normal because it was a brand new amp when I bought it.

    AfterEffectBass,
    I agree the answer is to contact Hartke. I'd like to know if they took care of your problem. These companies love taking our money. The real test is how they address problems.
