remove the cap from the fuse holder.. The fuse cap should come out from its housing
with the fuse held inside the cap. Take the fuse out and replace it with a new one.
WARNING: For continued protection against fire hazard only replace the fuse with
the same type and rating as was originally specified for the preamplifier. If you
have problems locating the correct fuse contact your VTL dealer or the VTL
factory service department.
Cleaning
Your VTL preamplifier should be dusted occasionally with a damp non-abrasive cloth.
You should not use any solvents for cleaning the front panel, as this can damage the
lettering and the finish.
Troubleshooting
1.
When I power on the preamplifier, Status LED does not come on and
nothing else happens. What should I do?
Check to make sure that the power cord is properly connected to the
preamplifier and the AC outlet. If there is no problem with the power
source, check the fuse unit in the back panel of the preamplifier. If the fuse is
blown, change the fuse. Turn the power on the preamplifier again. If the
problem still persists, contact your authorized VTL dealer immediately.
3.
I am getting a noise and hum coming from my system when I turn the system
on. What can I do to eliminate the noise?
It is recommended that you connect as many components as possible to a
good clean AC ground in your system for optimum noise reduction and safest
operation. If however there are too many paths to ground then a ground loop
hum can result, and you should either contact your dealer or the VTL factory
to try to resolve this problem.
5.
I am getting a ringing noise from the preamplifier when I touch or bump it.
What should I do?
One or more of the tubes in the preamplifier may be the source of the
problem. Follow the procedures listed in this manual to remove the tubes and
change them for new ones.
6.
I am getting a popping noise or intermittent noise from the preamplifier.
What should I do?
