Troubleshooting
In the unlikely event that your SVT-3 PRO should malfunction, take a few minutes to troubleshoot it before you call for
service. You can save yourself time and 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 informa-
tion. Also, you should refer your amp for servicing if it gets dropped, has liquid spilled into...

Ampeg reserves the right to change specifications without notice.
