An apparatus for driving a reactive load, comprises a plurality of N multi-input elements N greater than or equal to 2, connected in parallel, capable of amplifying a band of frequencies. Two inputs of each element can be connected to sources of direct-current voltage. Each circuit element and elements connected to its inputs define a circuit stage. N means, each means connected to at least one of the inputs of the circuit elements, are capable of equalizing the gain of each of the N stages within a prescribed percentage. A transformer having N primary, input, windings and one secondary output, winding, is connectable to the load. Each of the N primary windings have their inputs connected to one of the inputs of the circuit elements. The transformer is so designed that its impedance, usually inductive, as seen from the load, balances the capacitive load, to be connected to it, over the bandpass of interest. Author
