    UH OH...

    my 5150 head is going weird on me.... sometimes when im playing on the lead channel, it will suddenly just go super quiet. i dont know whats wrong, as i am not a big amp guy, i really dont know anything. I checked all the tubes, both power and pre amp seem to be all lighting up as bright as they did when i first put them in, theyre the right tubes and all. any other reason why this could be happening? i have the impedance set to 8 ohms as it says 8 ohms on the back of the cabinet hmmm....

    My Marshall used to do that ...turned out to be a dodgy speaker lead.
    Faulty patch leads can affect the signal too.
    If it's not somthing simple like this I'd definitly recommend getting a tech to look at it.....and get him to make the valves run hotter by changing the bias while he's at it!!... it'll sound sweeet!
