The T10 mc transformer is now available. It has been our experience that the best results are achieved when using moving coil cartridges loaded via a correctly matched transformer. The T10 contains two wide bandwidth, custom manufactured transformers with MuMetal cores. These have a natural unloaded ratio of 15:1. The T10 also includes the provision to alter the load seen by the cartridge. It allows different secondary load resistances to be placed across the secondary winding of each transformer. These, acting in parallel with the load resistance (typically 47Kohms) of a phono stage are reflected through the transformer to the cartridge. An optimum loading for the cartridge chosen can be readily found by ear. The transformers have a step up ratio of 1:15 and a provision to adjust the cartridge loading between 30, 50, 75, 100 and 200 ohms.
