    Description

    Step Up Transformer MAIHAK Malotki 500ohm : 50kohm ( 1 : 10 )
    This Step Up Transformer MAIHAK Malotki is a Step Up Transformer for a MC cartridge and a phono pre-amplifier within 47 kohms input impedance.
    This Step Up Transformer MAIHAK Malotki consists of two identical and matched MAIHAK transformers installed inside the case as you can see in attached picture.
    Refer to the 20hz, 100hz, 1khz, 10 khz, 20khz square waves very good output response in attached photos.
    Refer to the 20 - 20000 hz sine wave output response FFT analysis in attached photos
    Input impedance   :  500 ohm  ( excellent for stereo MC cartridge or mono MC cartridge less than 500 ohm output impedance)
    Output impedance :  50 kohms ( excellent for a phono pre-amplifier within 47 kohms input impedance)
    Step up ratio (voltage gain) :  1 : 10 (20dB)
    Frequency response : 10 - 20000 hz
    Clear and detailed dynamic sound for MC Phono Cartridge.
    I have tested this Step Up Transformer MAIHAK Malotki with MC Phono Cartridges of Ortofon MC70 (output impedance 2 ohms), MC Quintet (output impedance 7 ohms) and DENON DL-103 (output impedance 40 ohms), then excellent match with them.
    Input impedance of step up transformer must be higher than the output impedance of MC phono cartridge and
    output impedance of step up transformer must be similar to the input impedance of phono pre-amplifier for good match.
    Tin plated German wire is used for hand wiring within this Step Up Transformer by myself who has over 40 years theory and technical practice experience.
    Hand made case.
    Please refer to the attached photos.
