Conversely, a transformer with a turns ratio of 1:2 would be called a step- up transformer since its secondary voltage would be twice that of the primary. Since a transformer does not create power, the power output from the secondary of an ideal transformer can only equal (and in a real transformer only be less than) the power input to the primary.

This now provides a gauge to evaluate step-up transformers by - namely the step-up ratio (ratio of secondary windings/preamp input side to primary/MC cartridge output side). Be advised that the impedance is transformed by the square of the turns ratio. So a 20:1 step-up transformer provides a 400:1 impedance change.

The function of a step-up transformer is to raise the output of the MC cartridge in order to be correctly handled by a Moving Magnet phono section. At the same time, the step-up transformer adapts the impedance of the signal produced by the MC cartridge to an impedance that can be "seen" by your Moving Magnet input.

This transformer also needs a high coupling, low capacity wind. We at Electra-Print Audio tried a few arrangements of step-up and settled on a 1V to 8V gain, which offered an impedance of 10kΩ from 150Ω source. This worked well with a 10kΩ high-quality audio taper as a constant load and a means to vary the gain for the amplifiers.
