CrAnkPot MC STEP-UP TRANSFORMER

MORE ABOUT

ST-1C

Custom Crankpot ST-1C is a specially designed unit to maintain audiophile grade sound transparency. Our MC Step-up Transformer is a result of hours of focused listening to black vinyl while verifying various configurations of different transformers with divergent materials designed to shield the sensitive electronic equipment. Neither the wires, RCA sockets, isolation of the housing nor the material with which the box is made was chosen randomly.

ST-1C is equipped with a pair of custom handwound transformers developed to use the amorphous magnetic circuit and massively shielded against static or low-frequency magnetic fields. The elements selected and tested with highest precision are placed in a handcrafted wooden box. The inside of the housing is layered with a cooper foil in order to protect the item completely from the static and non-static electric fields – known as the Faraday’s cage. Thereby the main facet of our MC Step-up Transformer is its lack of characteristics facilitating the uncontaminated amplification of the signal to ensure an ideal reproduction of the originally recorded sound.

Custom Crankpot MC Step-up Transformer is entirely handmade
The transformers can be configured for three various gain settings: 14dB, 20dB or 26dB
ST-1C is provided with the original High-End Performance Pure Red copper RCA sockets CMC 805-2.5-CU-R, High-End Performance Binding posts CMC-858-S-CU-R for grounding and High-End Silver wires

DETAiLED

Gain Settings

14dB, 20dB,26dB (depending on the specifications of Moving Coil Cartridge) Owing to the very weak signal passing through the transformer's primary winding, the gain change is configured by resoldering of the wires, given that no switch is appropriate for this task

Input Impedance

120 ohms for 47 k ohms

Nominal Input Level

1mV for 14dB 0,5mV for 20dB 0,25mV for 26dB

Output Impedance

10 k ohms

Nominal Output Level

5 mV

Recommended Load Impedance

47 k ohms

THD Output Level

≤ 0,003% 150mV/15 k ohms
