Supermalloy MC Step-Up Transformer
In good condition 9/10

Due to the technology they use, MC cartridges have very low output, often around one-tenth of a Moving Magnet's (MM) output, which means they require more gain from a phono stage in order to be played at normal listening levels through your hi-fi system.
Where phono stages, as part of their signal amplification, will have a constant resistive input impedance, Step-Up Transformers have an input impedance that is frequency-dependent. Step-Up Transformers are also passive (i.e. not mains powered) devices, which also reduces the chance of external electrical forces impacting the cartridge's low output signal. The result of a Step-Up Transformer's design is that they are able to amplify the MC output level and produce less harmonic distortion as the frequency rises - which is the opposite effect of a phono stage. This results in a cleaner electrical signal and more dynamic sound performance from the cartridge in a wider, deeper soundstage.
Step-Up Transformers still require a phono stage in the system, for "active" amplification and RIAA equalisation, so they are connected between the turntable output and a phono stage. However, the phono stage will now need to be set for an MM-type signal, typically at around 5mV/47kΩ. This reduced gain requirement allows the phono stage to perform to its fullest potential, for greater sound performance.
