Air cores A physical core is not an absolute requisite and a functioning transformer can be produced simply by placing the windings near each other, an arrangement termed an 'air-core' transformer. Source: Internet
A power supply using a transformer with several windings, one or more rectifiers (which may themselves be vacuum tubes), and large filter capacitors provided the required direct current voltages from the alternating current source. Source: Internet
Different portions of the winding, accessed with taps, act as primary and secondary windings of the transformer. Source: Internet
