Ameritrons innovative pulse tuning technology lets you tune your amplifier at full peak output power for best linearity. It keeps average power to a low safe level to prevent overheating and power supply stress. "Why cant I just tune up at low power to reduce overheating and component stress?" you ask yourself. Well you can... but if you dont re-tune at high power (which causes overheating) you can create severe splatter and abuse your tube grids because of excessive grid current.
