  • Fender Roc Pro 1000 Hybrid head cuts out?

    hi guys

    my other guitarist has a fender roc pro head, and well it sounds pretty good,

    however, it keeps cutting out while we play.

    Now he tells me, hes NEVER changed the 1 tube in it (has no idea about the tube inside) and its dated 1993.

    He also told me it went from taking about 30 seconds to warm up, to 2-3 minutes.

    To me, that says BAD TUBE! but im not much on hybrid amps

    So i popped it open today, cause i guess one other guy had already resoldered the tube connections, and never bothered to look at the tube..it was covered in this tight grey rubber, which after i peeled off, the tube was chared black on top, more than usual

    You guys think just replacing the tube would fix the problem? its a 12ax7 preamp tube, thats it.

    Newb question i know, but im new to tube amps. Hopefully thats all it is, cause right now all we have to listen to is his 120watt crate head

    thanks in advance

    It wouldn't hurt to try. And it'd be a cheap fix. :thu:

      thats what i thought, i just figured since the thing was wrapped in there tight it didnt seem like too much tube changing was intended

        I can't believe someone would actually post the question w/o first at least throwing a different tube in to see if it was indeed the problem.:wave:
