A constant current transformer for gas-discharge tubes consisting of an aluminum can containing an iron core made of grain-oriented magnetic sheet material in split-tape core form with electrically isolated primary and secondary windings. The core has gaps on opposite sides with non-magnetic spacers. Stray field yokes are provided adjacent the gaps. A series-resonance capacitor is included in the can. The active parts fit tightly against the can, which serves to carry away heat losses. The parts are impregnated in the can using an epoxy resin in an overpressure centrifuging process. The primary and secondary windings may be connected outside the transformer in a voltage-adding arrangement in series with a load. Two or more transformers may be connected with their primaries in parallel and their secondaries in parallel with a load so that their currents are added, or with their secondaries in series with a load to add their voltages. An inductance may be connected in series with the series-resonance capacitor.
