The Torpedo Captor X is a load box. This term indicates that the Torpedo Captor X is a load which can
electrically replace the speaker cabinet while dissipating (transforming into heat) the power coming
out of the amplifier.
The Torpedo Captor X is a reactive load. A reactive load simulates the complex impedance of a real
speaker.
Always connect the speaker output of your tube amplifier to an
appropriate load (speaker cabinet or load box). The Torpedo Captor X is
such a load. The Torpedo Captor does not need to be powered up to act
as a load box. The maximum admissible power of the Torpedo Captor is
100W RMS, your amplifier shouldn't be set to play at a higher output
power value. See
100W.
2.2 Which output volume for my amplifier?
The correct use of your amplifier with a load box requires some precautions. Because of the silence
while playing, it is much easier to accidentally run your amplifier beyond the reasonable limits set by
the manufacturer than when using a real speaker cabinet with it. This can lead to faster tube wear
and, in some cases, more serious and permanent issues.
When first testing the amplifier at high volume, monitor the color of the
tubes and the general state of the amplifier. Red-glowing tubes or any
appearance of smoke are signs of a problem that may result in partial or
complete destruction of the amplifier.
Keep in mind that the "sweet spot" - the perfect running point of the amplifier, the one that will give
you the tone you're looking for - is rarely obtained at maximum volume –
showing this. In addition, the volume control of the amplifier is usually logarithmic, which means the
volume goes up quickly on the first half of the potentiometer rotation, reaches its maximum at 12
o'clock, and doesn't change much beyond this point. Therefore, you can reach the maximum volume
of your amplifier even if the volume potentiometer is not set at maximum.
By reaching the maximum output power of your amplifier, you will hear a lot of distortion, which may
not sound as cool as you may hope. In fact, most amplifiers sound pretty bad at maximum volume.
Always keep in mind that your amplifier may not have been conceived to be used at maximum
volume for a long period of time. Running an amplifier at high volume will cause premature wear of
the tubes and possible malfunctions or damages at the output stage.
The fact that the volume control of your amplifier is not set at maximum
doesn't mean your amplifier is not running at maximum volume. A good
habit is to keep the usual volume setup you would use in rehearsal or on
stage, rather than just following what the volume potentiometer indicates.
