The circuit design of the device includes several cascades, which use radio tubes from the Slovak manufacturer JJ: four double ECC83 triodes, two double ECC82 triodes and an EZ81 tube rectifier. The phono corrector uses four boost transformers (two per channel) equipped with super-permalloy cores to increase performance.

    The Luxman E-250 uses an NF-type RIAA correction scheme that uses negative feedback and provides a high signal-to-noise ratio. Boost transformers equipped with super-permalloy alloy cores perform the signal amplification of MC cartridges. At the same time, the switch on the front panel allows you to choose one of two options for the gain and input resistance for MC heads: 57 dB/40 ohms or 66 dB/2.5 ohms.

    The device supports the operation of MM and MS cartridges. For the former, balanced and conventional inputs with a new step-down transformer are provided, in which the core is made of high-purity permalloy. The input stages are built on several FET transistors connected in parallel sequence. The amplifier is quite traditional with general feedback.
