Description: I've owned this receiver for three years and have used it a few times for vinyl and FM only. Perfect working order, serviced at Sound Audio Repair in Olympia WA in August 2023. It does not have the quad chip and will require that for playing quad mixes. This listing is for the receiver only. Items in the last photos for visualization, speakers and shelf are also listed for sale.Online Details:A stereo/quadradial receiver with an AM/FM tuner and integrated amplifier with power output of 2 x 70 watts RMS into 8 ohms or 4 x 25 watts RMS into 8 ohms, housed in a metal case (a wooden case an optional extra).

With a "Vari-Matrix" circuit which simulates 4 channel sound from 2 channel stereo sound and will reproduce any discrete 4 channel program as well as stereo and mono.
