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. The transformers have a step up ratio of 1:36 switchable to 1:18 and therefore allow for the adjustment of cartridge loading between 36 and 144 ohms.
