An electrode assembly for use in an electrical discharge acoustic source, comprises a conductive tip holder 54 that can be connected to a power supply (12 figure 1), a discharge tip 52 connected to the conductive tip holder 54, and an insulating collar 60 surrounding the connection between the tip 52 and the holder 56 and having an aperture through which the discharge tip 52 projects. The tip is held in place by a sealing O ring 58 which negates the need to make a groove in the tip thereby reducing the weaknesses a groove causes. A series of multiple pairs of such electrodes can be configured and a switching arrangement can be configured so that any capacitor can be connected to any one of the pair of electrodes. These electrodes can be used in a Plasma gun used over a large range of sea depths.
