$300,- US I presume, is a lot of money. It is 2channel/4 channel quad and has no pre out / main connectivity. Is dificult to work on with unobtanium drop in parts. And this particulair receiver is in bad condition. But hè what is it worth to you and why? I owned this receiver while living oversees in original mint and working condition and traded soon after purchase it in for another 2/4channel with pre out Pioneer separate / integrated amp. And that was while I was still completely into quad and Pioneer. If you are a re-seller audio 'flipper' (which I am not, never was or will be); I doubt if you make a profit on it. Vintage Quad is NOT sought after, no matter what and who ever tries to convince you otherwise. It is only populair by a very small group of 4channel stereo enthusiasts / collectors. Having said all that, mine at least sounded great, and this receiver is definitely a piece of art!
