Hey Dean,
It was the stands that the speakers are on that threw me off (could have been a special order or just made for the video itself), but the entire system looks like vintage Electrohome to me. They are a Canadian company and made many "space aged" systems like the one seen in the video, back in the 60's/70's. I think they are still in business, too. Hope this helps.

Update: Click link and scroll down to nearly the bottom of the page. I think you will find what you are looking for. I still believe the electronics are from Electrohome, but it was the speakers that had me scratching my head. The sad thing is that I don't think the speakers are real. The website is dedicated to media props. Cheers!
