Voltage selector
This selects the correct mains voltage for your territory. Please refer to a qualified
technician before even thinking about moving this switch. If you do find yourself in
foreign climes where the mains voltage is different to home, (and the water tastes funny),
it will be necessary to switch this selector. The mains fuse must always be changed at the
same time. Failure to do this will result in either the mains fuse blowing as soon as the
amp is turned on or the amp running with a fuse that is of too higher value to provide
adequate safety protection. Generally, the fuse value will double if the mains voltage is
halved, (i.e. if it’s a 1A fuse in the UK @ 230V, it will needs to be a 2A fuse for the USA @
115V).
Always use the correct rating and type of fuse. Victory amplifiers exclusively use UL-
approved 20x5mm glass ‘T’ or ‘Timed’ fuses. If you have difficulty acquiring the correct
fuses, please contact Victory using

Please only use the correct mains cord for your territory!
HT FUSE
The HT or ‘High Tension’ fuse protects the high voltage for the valve supply. If this fuse
blows, the first step is to replace it with an identical T500mA 20x5mm fuse. The HT fuse
may sometimes blow due to ‘flash-over’ inside an output valve. This is where during the
manufacturing process, not all of the gas is removed from the glass envelope and the
‘getter’ inside the valve, usually made from barium or magnesium oxide, will burn or
evaporate these remaining gasses resulting in the common silvered internal surface of the
valve. This process, which is more likely to happen with new equipment, draws high
current momentarily and can blow the HT fuse. It will rarely cause any damage so just
replacing the fuse is sufficient to get the amp running normally again.
However, if the HT FUSE repeatedly blows, it may indicate a serious valve failure where
internal parts of a valve are shorted and in this case the amplifier needs to be checked by
a qualified engineer to assess the problem.
