About the Rothwell MCL Moving Coil Step-Up Transformer
The Rothwell MCL Moving Coil Step-Up Transformer is engineered for audiophiles seeking optimal performance from low-output moving coil (MC) cartridges. Utilizing high-quality Lundahl transformers from Sweden, the MCL is designed to interface MC cartridges with moving magnet (MM) phono stages, making it ideal for valve and MM-only phono preamps. The unit features a 1:20 turns ratio, providing 26dB of gain, and maintains a 100-ohm input impedance for broad cartridge compatibility. Its construction employs cobalt-based uncut amorphous strip cores and carefully designed loading networks to ensure very wide bandwidth (8Hz–75kHz), low distortion, and excellent transient response. The MCL is housed in a robust chassis and is recommended for cartridges with outputs between 0.2mV and 0.7mV and internal impedances below 20 ohms. Dimensions are approximately 60 x 155 x 92 mm, and the unit weighs 580g.
