    troubleshooting Ampeg B-15-N base amplifier.
    I have a Ampeg B-15-N amp that hasn't been used for a long time. I can't get any sound from either channel. THE 5U4GB AND 6L6GB TUBE HEAT UP. THE 6SL7GT TUBES DON'T HEAT UP. THAT IS THE EXTENT OF WHAT i KNOW ABOUT TROUBLESHOTTING. I woul appreciate any help I can get .
    ThanksBill

    Hi there

    The fact that you don't know much means that you should take it to a tech. Live voltages inside tube amps are lethal.

      Now you know why it hasn't been used in a long time.

        With no technical skills, you could try is replacing the 6SL7GT tube.
