Troubleshooting
In the unlikely event that your SVT-2 PRO 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 you think the problem may be worn out tubes, see page 7 for
symptoms of tube failure.
If the problem isn’t
covered here, or if
the steps led you to
“Service Amp”,
then contact your
Ampeg dealer for
service information.
Also, you should
refer your amp for
servicing if it gets
dropped, has liquid
spilled into it, or
sustains damage to
its power cord.
Disconnect all external devices
except bass and speaker cabinet
