Its a Grundig almost 100% sure. The real high end had Dual turntables only the lower or shadow brands had Philips. Grundig also made a brand called Lumophone you will never see that name but I know becouse I found one in a antique store in BC Canada and its was exactly like the Grundig. I have seen a floor model Grundig that looks just like your Atlantis. If i find the paper work on this model i will email it to you. For some reason the Grundigs under the odd labels found their way up to Canada.
