SVT-350H
Troubleshooting
In the unlikely event that your SVT-350H should stop working properly (or just stop working), take a few minutes to trou-
bleshoot it before you call for service. You can save yourself a lot of time and sometimes money by doing it yourself, and
often the cure for the problem is something quite 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.
