Dead Deluxe Reverb Reissue, first checks?

    A month ago a fuse popped in my DRRI. A replaced fuse brings the power light back on, but no sound. Are there any components I can check easily at home before resorting to taking it to a repair shop? (Not going inside the chassis, a skill set and knowledge I do not possess).

    Speculation welcomed. Repair shop probably likely. Amp is like new otherwise, but 10 or so years old.

    Try looking at all the tubes and see if they are lit up or getting warm.
    Does the standby switch feel normal when operated ?
    If nothing obvious is found you are probably looking at an internal problem.

    Not much you can do without a tube tester, make sure the speaker is plugged in? I wouldn't run it too long like this.

    Have you ever changed the tubes? This is what i suspect. Unfortunately when a tube goes bad they can take other stuff with them.

    If the amp was sounding good prior to the fuse going out chances are it's a bad power tube. Try changing both power tubes and see if it works. As Wildeman stated above a tube failure can cause other parts inside the amp to fail. But at least try replacing the power tubes before a trip to the repair guy.

    Yep, tubes #1. Especially the rectifier or power tubes.

    Thanks guys, I'll give that a look tonight. I may swap in some other tubes from functioning amps to see if that "rectifies" the situation.

    Yes, try the rectifier first. It's on a different secondary winding than the
    Power lamp.
