Detachable Power Cord System

 

 

OUTPUT TRANSFORMERS:

The Cyber 845 output transformer is manufactured by selected silicon steel in c-cut form. The primary and secondary coil is wired with a special technique to achieve close coupling. Traditional paper and varnish is used for coil insulation and historical damp proofing techniques are also applied. These transformers are visually impressive but even more impressive is their ability to a deliver smooth solid and musical deep-bass. A secret revealed how to increase dynamics and liquidity.
