21. All aspects of Key Output stage 1 were completed by mid-2012, in time for the London Olympics. 22. The load peak current will be limited by the maximum current limitation of the AC output stage . 23. These four pressure modulators consist of one inlet and one outlet valve, controlled by electronic output stages . 24. The original output stages used triode-connected KT66 tetrodes, although a 6L6, with slightly lower output, could be used. 25. A " class-A amplifier " is distinguished by the output stage devices being biased for class A operation. 26. The picture above shows positive supply voltage of the output stage and the voltage at the speaker output. 27. The audio output stage , for instance, had a larger cathode, and warmed up more slowly than lower-powered tubes. 28. Vacuum-tube output stages in early wideband oscilloscopes used radio transmitting tubes, but they consumed a lot of power. 29. This input stage drives a common gate amplifier as the output stage , with output signal " V " out. 30. This in turn can cause a reactive pulse of high voltage that can destroy the transmitter's final output stage .
