Reverb Footswitch socket
Connect the supplied single way latching footswitch here to switch the internal Digital Reverb ON/OFF
Single Ended Mode switch.
This switch, located through a hole in the rear grill, is used to switch off either of the 2 output valves.
This results in the amplifier running ‘single-ended’ which is a very pure Class A mode. If the front panel
power switch is on LOW, in single-ended mode the V40 produces around 0.5 Watts rms. This should
allow playing at home without getting lynched by the neighbours. The switch throws both ways to
alternate between each output valve for even wear if this mode is used extensively.
However, even this very low output power can still be very loud so be aware of who you may be
affecting. Victory takes no responsibility for any physical abuse that may result from your playing.
Biasing:
Whenever any output valves are changed, the amplifier will need to be re-biased. This must be done by
a qualified or competent person as there are lethal voltages inside the V40 and getting killed by a guitar
amplifier is a rubbish way to die. Also take care as valves may still be very hot from use. Use a cloth to
remove valves if possible. Take care when removing any valve as the pins can easily be bent and the
plastic locating key on the output valves can be snapped off. We recommend a slow circular motion
known a ‘dweezling’ while lifting the valves from their bases as this will free them with the least amount
of effort and stress. Ensure that as you remove them that they are never more than a few degrees from
vertical to avoid bending or breaking pins etc.
Please always try to buy matched pairs of output valves as they will be easier to Bias and give longer
service. Ensure the toggle switch on the top of the chassis is in the correct position for the selected
output valves, (either 6L6s or EL34s). The V40 Duchess ships with EL34 output valves fitted.
