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 information. Also, you should refer the amp for servicing if it gets dropped,
has liquid spilled into it, or sustains damage to its power cord.

The SVT-3 PRO is covered with sheet metal and aluminum, not unlike robots, spaceships and other
cool things. Clean with a dry lint-free cloth.
Never spray cleaning agents on the SVT-3 PRO. Avoid
abrasive cleansers which would damage the finish.
