Abstract: This invention relates to a lute comprising a body-shaped sound box and a neck attached thereto. The sound box is made up of a domed rear section and a cover. The aim of the invention is to provide a lute which can meet the needs of modern concert performances and be used by contemporary guitarists, whereby the excellent sound qualities of the lute are retained and the instrument can be used in a modern-day orchestra. This is achieved by providing the cover and the string-holder with a outwardly curved shape; a surface that is devoid of any transverse beams is arranged on the underside in an approximately symmetrical position with respect to the string holder and said surface is configured as a strip-free surface or fitted with strips which are symmetrical with respect to the center axis.

Abstract: The invention relates to a bi-polar power supply for a plasma chamber including an adjustable DC power supply having a positive output terminal and a negative output terminal. A transistor bridge circuit having two input bridge terminals is coupled to the positive and negative output terminals. Two bridge output terminals of the transistor bridge are coupled to the plasma chamber. A current detector is coupled to the two bridge output terminals for detecting the current flowing to the plasma chamber and controlling the transistor bridge circuit to provide a bi-polar power supply to the plasma chamber.
