The Bev is different also from any other present day ESL in the way it uses charge; there is no need for a separate bias supply. The diaphragm is low resistance type. Looking at the amplifier schematic (which I do have), I do agree it looks weird and do wish I could get someone to look at it who could update the circuit and possibly convert it to a balanced input. The equalization on the Bevs was needed to compensate for that acoustic lens through which the output of the speaker has to pass.
