Technics - SA-DX930 - SL-PG390 Hi-fi set

From my personal collection, I propose a Technics black finish stereo receiver (sintoamplificatore) and CD player from the famous Japanese house TECHNICS. Recently cleaned, checked, and serviced by an industry specialist. Complete with the original remote control for the amplifier (some signs on the back as in the photo) and ORIGINAL Technics power cables. They are presented in excellent mechanical condition and very good cosmetic condition. Some inevitable signs of wear, evaluated from real photos.

The Technics SA-DX930 is a 5.1 Home Theater stereo receiver launched on the market in 1999. It is known for its robustness and for using Class H+ amplification, Technics' proprietary technology that optimizes energy efficiency while reducing harmonic distortion.
