The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics.In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of ...
The Original 2–12 Vintage is 100 watts, whereas the 6–10 and the 1–15 are only 50 watts The original Classic was a 50 watt amp and two 12-inch speakers and a spring reverb, with two preamps for "clean" and "distortion" channels.
An amplifier that is said to have a gain of 20 dB might have a voltage gain of 20 dB and an available power gain of much more than 20 dB (power ratio of 100)—yet actually deliver a much lower power gain if, for example, the input is from a 600 Ω microphone and the output connects to a 47 kΩ input socket for a power amplifier. In general ...
In the one-person operation, Alexander "Howard" Dumble (June 1, 1944 – January 16, 2022) [1] [2] made each amp personally. Because of this, Dumble amplifiers are the most expensive boutique amplifiers on the used market, [ 3 ] and prices have risen rapidly.
It was the most popular amp of this era, with most amps surviving from this era today being Deluxes. The rarest of all the original 'woodie' series was the Professional. It was the largest of the trio featuring Jensen 15” field-coil speaker and 6 tubes delivering 25 watts of power. [3]
The volt-ampere (SI symbol: VA, [1] sometimes V⋅A or V A) is the unit of measurement for apparent power in an electrical circuit.It is the product of the root mean square voltage (in volts) and the root mean square current (in amperes). [2]
