Bellari MT502 mu Moving Coil Step-Up Transformer

The Bellari MT502 mu is a hand-built, stereo, moving coil step-up transformer that is designed to raise the low-level output of a moving coil cartridge to a moving magnet level. This makes your moving coil cartridge compatible with your phono preamp. The MT502 is all hand-built in the USA and features hand-wound coils, gold-plated inputs and outputs, and a ground lift. It is a highly regarded component, recommended by Stereophile for several years in a row.

The MT502 features a selectable turns ratio, which means that you no longer need to match your cartridge with a step-up transformer. With the selectable turns ratio switch, the MT502 can match almost any cartridge. The 12:1 ratio is designed to work with cartridges like the Denon DL103 or 103R or similar, while the 30:1 ratio is designed to work with cartridges that need more gain/level. The mu in MT502 mu stands for Mu Metal, the new metal used in the transformer's encasing. Mu Metal is a high-quality shielding material that ensures optimal performance.
