Power Scaling is a proprietary technology London Power developed to allow the maximum power of an amplifier to be dialed down to whatever level you need. Most Tube amplifiers have a „sweet spot“, this occurs when the amplifier’s power tubes are pushed into what is known as „clipping“, „break-up“, or „saturation“. The tone and harmonics being produced by the amplifier in this state is why the majority of guitar players prefer vacuum tubes. Unfortunately, in order to get an amplifier into the „sweet spot“ the associated louder volume can be very undesirable. Power scaling allows the user to keep the „sweet spot“ at any volume!
Unlike power attenuators that are placed between the amplifier and the speakers – causing the amplifier to „cook itself“ and seriously shorten tube life. Power Scaling allows the power output stage to be variable from full volume all the way down to bedroom levels while still achieving power tube „break up“. Other advantages of Power Scaling are longer tube life at any setting less than maximum. When the Power Scale control in the minimum position the amplifier is now in standby thus eliminating the need for a standy switch.
