In the event that your
SVT CLASSIC should stop
working properly, or just
stop working, take a few
minutes to troubleshoot it
before you call for service.
You can save yourself a lot
of time and sometimes
money doing it yourself,
and often the problem is
something quite simple.
Please refer to the
Troubleshoointg Diagram
for guidelines. If you think
the problem may be worn
out tubes, see page 7 for
symptoms of tube failure.
DISCONNECT all external devices
except bass and speaker cabinet.
No sound, bad sound?
LED's on?
Power LED green?
Green Bias LEDs on?
Instrument volume up?
Sound OK?
Go for it!
Check AC outlet, power cord,
power switch, fuses. Retry
Check Standby switch (20 second
delay when first turned on). Retry
Rebias or see Page 7 for
possible faults. Retry.
Set controls. Retry.
Bias LED's flashing red
with signal?
Possible power amp
problem.
Check speaker cables.
Retry.
If these steps fail to solve
problem, see below.
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 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.
