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 3.15A fuse in the UK @ 230V, it will need to be a 6.3A 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

Mains Inlet, (IEC Socket)
Please only use the correct mains cord for your territory!
Mains Power Switch.
The mains switch turns your amplifier ‘ON’. Ensure the front panel toggle switch is in the middle,
‘PREHEAT’ position before turning on the mains.
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 T1A 20x5mm fuse. The HT fuse may sometimes blow due to ‘flash-
over’ inside an output valve. This is where during the valve 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 in the
first 50 hours of use, 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 consistently 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.
VERY IMPORTANT WARNINGS!!
In certain countries, (specifically, Nordic countries), is it totally forbidden to open up any electronic
equipment or to work on them at all unless you are a fully qualified and approved technician. Please
check the laws in your country and do not attempt to change valves/tubes or re-bias the amplifier if the
law forbids this. In this case, please take your amplifier to a qualified and approved electronics
technician.
In certain countries it is also totally forbidden to keep or place any liquids on top of the amplifier, (e.g.
beer, water bottles, glass, drinks etc). This may cause serious electric shocks and/or dangerous
situations.
Also, it is totally forbidden to use the amp in the event of rain splatters/water drops getting into or onto
the amp.
Even if it is not a law in your country, you should never allow liquids near the amplifier or attempt to use
the amplifier if it has been subjected to any moisture as this could result in a fatal electric shock.
BIAS ADJUST
Biasing needs to be done each time the output valves are replaced and should be checked periodically to
make sure they are working at their optimum for sound quality & valve life.
Firstly, there is a small chrome toggle switch on the top of the chassis just above the Bias section which
sets the voltage range for a choice of output valves. The rear grill needs to be removed to gain access to
