  • HELP! Amp volume cut out and now there is no sound!

    Amp is a PT100.



    So I was practicing for about an hour when the volume suddenly decreased and then completely cut out. Now there is no sound whatsoever. NO hissing or any type of noise at all.



    I unplugged my pedal board, disengaged the loop, and plugged straight in with a couple guitars and still no sound of any kind. All 4 powertubes light up...



    What say ye? Bad preamp tube? BLown fuse?

    Replace the fuse(s) first. Replace it even if it looks good.
    Rig:
    Ibanez S2170FB
    Soldano X88R Clone Preamp
    TC Electronic G-Major 2
    50W EL34 Rack Power Amp
    Lopo 2x12 Cab.

    Stuff I've built:
    5W tube amp (1 12AX7/1 EL84)
    Ruby Cigar Box Amp
    X88R Clone
    50 Rack Power Amp

            Fuse

            Preamp tubes

            Power tubes



            I'd check them in that order.



            Based on personal experience, I'm leaning towards preamp tubes.



            This happened to me once at a gig. I was playing in a 3 piece. My amp died at the very last song in our 4 set gig. If it's gonna happen, I guess that's the best time. The last half of the song was just the drummer and the bass player. For some reason, they told me that was the best the song had ever sounded.

                Plug your guitar into the loop return, if you get sound then it is more than likely a pre amp tube.
                Great deals with: Draco Aron X 2 , Holy War, Edge of Darkness X 2, freehandarson, Chrisjd, Yo_Squig, Crank, Abstract, xnatex, Norton666, JSilverstein, Elemenope, moop, Ricky Rockhardo
