    MY AMP BLEW UP! HALP!

    Hey guys.

     

    I accidentally ran my head (100-watt Marshall Superlead) for about 30 minutes without it being plugged into the cabinet. It ended up killing one of the power tubes (#4) and the High test fuse. I pulled the one and four power tubes, replaced the high test fuse and halfed the ohms to run the amp at half power.

     

    Is it better for me to repleace one and four with new tubes without biasing the amp, or run it at half power? 

     

    My band is on the road right now, so replacing all four and having the amp biased is not an option.

     

    Thanks in advance.

    I'd run at half power....whatever damage may have occured around 1 and 4 may make running them unbiased even worse than normal.

    ...then again, the resulting skraw could be the exact toan yer after........j/k

      Fix'd

      Those things never die...the CL's full of 'em. You can make your own 3x3 MayStack of'em for less than the cost of one Boogie.

      You probably should get the transformer checked. They can still work and be damaged. They will just be quieter and you might not notice the difference with it running at half power since you're already expecting it to be quieter.

      This. Just get a matched quartet and get it biased and be glad it wasn't worse.

      Maybe we should ask the experts in the amp forum! .png" alt=":smileysurprised:" title="Smiley Surprised" />

    One is late sixties / early 70s, and one is. A RI. "The gall." Bitch, please.

    We make enough money to be able to tour, but we certainly don't have an extra $100 laying around.

      Um, don't go on tour with gear you can't support. Take a lesson from the Melvins.

    I'm slowly realizing that this forum is primarily populated by people who are collectors of gear and not much more.

    And that's a bummer.

      think about that statement for a moment.  you, being a real touring legitimate musician, don't know how to work on your gear.  what you need is a forum of guys that study gear and don't play out, iow, techs.

       

       you need tech advice, go a tech forum, or listen to the advice given.

      Please don't expect forum people to run out and repair your equipment. That's a bummer.

      Ask SAL.  He's probably out on tour as well.  You fellows could probably hook up.

      Psh, everyone knows the amp forum is for posting pictures of fate tits that claim to be inside bikinis.

       

      He's in the right place for tech help.

    I guess you still don't know how bad the damage is.

    I would just use one amp until you can get it fixed, rather than risk making it even worse.

      It's fine.

      Just had a new quartet of EL34s installed and had it biased.

      Lesson learned.

      I love how on The A-Team they would fire a hailstorm of bullets and no one ever actually got shot.

      They also had a really sweet van.
