High voltage amplifier and low-noise linear power supply

High voltage amplifier is used to drive piezoceramic elements and is especially suited for piezoceramic tube scanner control. Device consists of three independent high voltage units for  x, y and z axis control with selectable gain and auxiliary offset and modulation inputs. Range of output signal is ±200 V (±350 V variant under construction). Both low and high voltage part is powered using low-noise linear power supply specially designed for this purpose.
