2. Sansui AU-11000 - Wikipedia

   en.wikipedia.org/wiki/Sansui_AU-11000

   The 2 circuits make up each power amplifier per channel. This makes a total of 8 power-output transistors within the amplifier. Each amplifier channel has a temperature sensor built-in as part of the power protection circuitry. If the amplifier is too hot, the power protection circuitry will not allow the amplifier to power on. The power ...

3. Linear amplifier - Wikipedia

   en.wikipedia.org/wiki/Linear_amplifier

   A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier , some of which have output power measured in kilowatts , and are used in amateur radio .

   The biasing of a push–pull output stage can be adjusted (at the design stage, usually not in a finished amplifier) between class A (giving best open-loop linearity) through classes AB1 and AB2, to class B (giving greatest power and efficiency from a given power supply, output valves and output transformer).

6. Regulated power supply - Wikipedia

   en.wikipedia.org/wiki/Regulated_power_supply

   Linear variable bench power supplies have existed since longer ago, dating back at least to the 1980s. [6] [7] [8] Linear power supplies typically make clicking sounds while adjusting the voltage, caused by adjustment between transformer taps. This is done to reduce energy wasted to heat by widening or narrowing the selected section of the ...
