Driver Amplifiers were used in hydro systems throughout the 1990's as part of the Electro-Hydraulic Interface
(EHI). They not only provide a method for controlling many different types of valves, but they also allow for
a separate manual control.

Unfortunately, when a Driver Amplifier fails, it must be replaced in order to move the wicket gates, blades,
