Very good amplifier produced by a reputable audio equipment manufacturer from Japan. ONKYO INTEGRA A-8250, made from 1985 to 1987 - the period when the best audio devices had been produced. Beautiful strong, detailed sound, especially when listening to the music from a turntable. With a complex section (has three impedance levels on a phono input, depending on the type of phono cartridge). Technically functional, everything works very well. Visually in a very good condition - as visible in the pictures. Shipping by a courier with a tracking option (Europe - continent). The rest of the World via Poczta Polska (Polish post).The item will be very well packed! I warmly invite you to participate in the bidding.
