What is a VVR in an amp?
VVR = Variable Voltage Regulator/Reduction is a method to control amp output power using modern mosfet technology. This control can be used different ways.
How does VVR work?
The VVR is a simple circuit that when installed in a musical instrument amplifier will make the B+ voltage and bias voltage variable from 100% power to a minimum power level which is selectable by changing resistor values. While it is a simple circuit it is not a simple mod to install.
What is London power scaling?
What is Power Scaling? Power Scaling’s goal is to achieve the same tone as one’s preferred “loud sound,” but at a much lower volume. The method can involve one of over sixty distinct approaches, each with many variations. Power Scaling™ is a methodology developed by Kevin O’Connor of London Power.
What is VVR control?
VVR uses the network to replicate data from the Primary to the Secondary. The Bandwidth Throttling feature enables you to control the maximum network bandwidth to be used by VVR for replication. VVR enables you to change the network bandwidth used for replication to a Secondary even when replication is in progress.
What is VVR in Veritas?
Veritas Volume Replicator (VVR) is data-replication software designed to contribute to an effective disaster recovery plan. VVR enables you to maintain a consistent copy of application data at one or more remote locations. It provides a consistent copy of application data at the remote locations.
What is amp power scaling?
Power Scaling, in the context of guitar amplifiers, is a method by which the overall volume can be reduced without impacting the saturated tone, harmonics and dynamics of a fully cranked amp. Power scaling can be applied to the power section, the whole amp or any stage in between depending on what is being implemented.
How does amp power scaling work?
Power scaling technology is able to reduce the POWER of a tube amp. The actual characteristics of the tubes stay unchanged. The sound of the distorted or overloaded tubes are kept the same. With Power Scaling I can, for example, use the JTM45 and reduce its maximum output power down to 125mW.
What does VVR stand for?

What is VVR replication?
Veritas Volume Replicator (VVR) is data-replication software designed to contribute to an effective disaster recovery plan. VVR enables you to maintain a consistent copy of application data at one or more remote locations. You can start using VVR in a VxVM configuration by installing a valid VVR license.
How do I reduce the wattage of my tube amp?
When removing output tubes you can do the following: Remove the two outside tubes, remove the two inside tubes, remove the first and third tubes, or remove the second and fourth tubes. This keeps both sides of the output stage in tact and effectively lowers the power of the amp.
What is VVR in banking?
VVR: Software Validation And Validation Report.
What does VVR stand for in HVAC?
VAV/VVR Variable Air Volume Controller. Installation Manual.
How to calculate the Hall voltage on the heart?
Calculate the Hall voltage induced on a patient’s heart while being scanned by an MRI unit. Approximate the conducting path on the heart wall by a wire 7.50 cm long that moves at 10.0 cm/s perpendicular to a 1.50-T magnetic field.
When did Edwin Hall discover the Hall effect?
The creation of a voltage across a current-carrying conductor by a magnetic field is known as the Hall effect, after Edwin Hall, the American physicist who discovered it in 1879. Figure 1. The Hall effect. (a) Electrons move to the left in this flat conductor (conventional current to the right).
Which is the correct formula for the Hall effect?
Section Summary 1 The Hall effect is the creation of voltage ε, known as the Hall emf, across a current-carrying conductor by a magnetic… 2 The Hall emf is given by ε = Blv (B, v, and l, mutually perpendicular) for a conductor of width l through which charges… More
Where does the current go in the Hall effect?
The field is perpendicular to the electron drift velocity and to the width of the conductor. Note that conventional current is to the right in both parts of the figure. In part (a), electrons carry the current and move to the left. In part (b), positive charges carry the current and move to the right.
