mc stepup transformer

We introduced the special coil winding structure used for T-1 (out of production) which established a very good reputation. Now we applied the technology for mass-production type MC Step-up transformer T-500 which we introduce this time. The merits of T-500 are its high sound quality and realization of low price.

Because a MC cartridge generates power through a coil, it conducts a "balance operation" at the both of beginning and end of winding. We release T-500 for high sound quality MC cartridge which has the input portion of "full balance correspondence" which optimize its specialty to the maximum.

The Model 411 II is mono-functional stereo MC transformer to match with MC cartridges with internal impedance (DCR) of less than 15 ohm. The impedance tolerance is 25 ohms. The transformer is a toroidal design that applies the toroidal winding to 0.05mm thickness of supermalloy, layered ring-core. The core volume has an external diameter of 25mm, internal diameter of 16mm and height of 10mm. The termination of the wire is directly connected to in/out terminal. Therefore, the high efficiency of toroidal transformer realizes extremely low loss structure. It delivers the signal from the cartridge without coloration to the phono- terminal directly. Model 411II is a modified version of Model 411 and it has 32dB of step-up ratio of approximately 40 times.
