Problems with Mesa Boogie 2:Fifty

Hey Guys, hope you can help me with this:

Yesterday I had problems with my new 2:fifty poweramp: I switched the power-switch on while the standby-switch was switched off and the volume-knobs were turned to zero, so far so good. Then I waited about a minute so that the tubes could prepare to be used (the manual sais, that you have to wait half a minute before you switch the standby to on position). Then I switchend the standby on and after that I heard a short buzzy and noisy sound and then the fuse was blown. So I changed the fuse and tried again to turn the amp on but the same problem appeared. What did I do wrong?

Thank you very, very much for your help and support!

I had a similar problem a few months ago when I got my 50/50. It turned out to be two bad power tubes. I ended up having a string of five bad Boogie power tubes in a row. Since retubing with JJ 6L6's it's worked perfectly.

Sounds like one or more power tubes. Check your manual for the troubleshooting section, it will explain how to figure it out.
