FLT Tamura series SUT

We at fonolab have been representing Tamura MC Step-Up transformers for a long time. After we worked with the top model SUT-83S, its simplified versions based on TKS models, and presented our original EQ LOAD correction module, we have decided to take a new look at Tamura transformers.

For work we have chosen the FLT series, that have an extended frequency range with the possibility of connecting cartridges with an impedance of 3 and 40 Ohms.

We offer various options for FLT transformer: from a simple model with a shortest signal path to the model with the presence of the EQ LOAD correction module.

We will be also happy to make designs with your special wishes.

FLT series features:

  • MC step-up transformer which has both ultra-wide band and ultra-small distortion
  • Permalloy toroidal core transformers (specially manufactured by Tamura Corp.) is used for each channel
  • The custom-made aluminum/copper case equipped with highly efficient internal damping materials
  • Stainless-steel non-magnetic screws to minimize the influence of the magnetic distortion; thereby the clear sound has been realized
  • LC-OFC is used for the wiring material
  • High quality Gold-plated brass RCA connectors with Teflon insulation
  • Suitable for almost all MC cartridges (Koetsu, Van den Hul, Ortofon, Lyra etc.) with LP playing of fine quality.


  • Input impedance: 3 / 40 Ohms
  • Output impedance: 4k Ohms
  • Frequency response: 10Hz to 100kHz (+-1.0dB)
  • Chanel separation: 60dB or more (20Hz-50kHz)
  • Ratio: 1:10 / 1:36
  • Phase characteristics: Within 10° (20Hz-50kHz)
