    So, I was playing an all day outdoor gig (the American Royal BBQ contest here in KC) and was trying out my new, very cool, and very kick-ass Trace Elliot AH600. Things were fine until later in the day, mid-set of course, that the sound kind of faded away. I tried a couple of different things-- shut it down, etc, and it did come back up. I finished the set and shut it down thinking it might have gotten hot. After 20 minutes or so, we came back for another set. I turned the amp on-- plenty of input but no output.
    So, if any of you have a schematic or know where I can obtain one, or have any suggetions for repair, please let me know. Thanks!

    Most people here don't have amp schematics, especially for a unit that is no longer in production. You might want to try contacting Gibson.

    Oh? Well thanks. I'll see if I can spend another couple of hours searching the net for the elusive information I need. :meh:
     
  5. Take it to a tech near you! Unless you are set on "fixing' it yourself!

    Good Luck.

    Right-- but I was going to have my friend (a EE major) take a look at it for me. He works for parts cost plus beer. ;)

    Did it make any sound at all after you shut it down?
    Or was it just not as loud?

    If it was not making any sound, it may have overheated - you may try adding fans for outdoor shows.
    Small fans can be purchased at Radio shack. I use 2 extra fans on my power amps during outdoor gigs.

    If it was just not as loud, it may have been a power problem. We always use line regulators when playing outdoor gigs as sometimes there is a drop in power. Computer line regulators typically cost less that rack line regulators from music companies such as Furman. Power conditioners are not line regulators.

    Thanks RN2W. That's kind of what happened. I was playing along and the sound just faded away. I changed a couple of settings, and it gradually came back up and I was bale to finish the set. When I came back-- there was nothing. I'm getting it back out of the band trailer today and I'll see if it works.

    Have your EE friend draw the schematic for it...it's an interesting exercise;)
