Troubleshooting

In the unlikely event that your PB800 should malfunction, take a few minutes to troubleshoot it before you call for serv- ice. Sometimes you can save yourself time and money by doing it yourself, and often the cure for the problem is simple.

If the problem isn’t covered above, or if the steps lead you here, then contact your Ampeg dealer for service infor- mation. Also, you should refer your amp to an authorized service center for servicing if it gets dropped, has liquid spilled into it, or sustains damage to its power cord (see page 3).
