The newly developed low profile, large capacity block capacitor together with a regulator circuit with discrete configuration that are used in the power supply circuit achieve the desired high quality power supply environment. The E-250 power supply circuit also features LUXMAN’s original round pattern board allowing the smooth transmission of the delicate sound signals.
The NF type equalizer circuit in the E-250 features many of LUXMAN’s original and custom built parts. This equalizer has a high S/N ratio which reduces noise by connecting the first stage FET in parallel. A monaural switch when playing a monaural record is provided as well as a low cut switch that cuts out low frequency signals that can be generated by distorted records.
