What is a Variac? - Tech-FAQ

WebUse 2: Gradual Power-Up. You can also use a variac when trying out an unrestored radio or TV for the first time, when its operating condition is unknown. The idea is to set the variac at a low level—say, 50 volts—and then gradually increase the voltage, carefully watching your set for any signs of trouble. WebAlthough they are intended to achieve the same result – namely reducing level without compromising tone or dynamics – the methodologies are quite different. In a nutshell, power scaling works by varying the B+ voltage inside the amp. Unlike using a variac, this allows the full heater voltage to be maintained at all settings. notts city council cameras
