If the problem isn’t covered above, or if the steps lead you here, then contact your Ampeg dealer for service informa- tion. Also, you should refer your amp to an authorized service center if it gets dropped, has liquid spilled into it, or sustains damage to its power cord. Regular cleaning and maintenance by your local Service Center will help extend the useful life of the amplifier.
