Hagerman Audio Labs: StepUp Moving Coil Transformer Variable Gain Variable Loading

"StepUp" MC Transformer

$649

The StepUp transformer is built around the CineMag CMQEE03440A, with the primaries wired in series to provide three selectable gain settings. Each gain setting has been tuned for optimal transient response via secondary loading. In addition, the cartridge can be selectively loaded through the use of primary side resistors. This split-loading topology maintains proper gain and bandwidth of the transformer for all configurations. Select the gain you need, then adjust loading to taste.
