Vintage Entertainment Center?
I have an old entertainment center in a basement called Airline Amphi-Theatre. It's got a record player, black and white television set and a radio. I haven't been able to find anything on the internet about it.
Model # GST6975-A
Production Code No. 424
120Volts, 60 Cycles, 300 Watt
Airline was the brand name for one of the big department stores, I think it was Montgomery Wards. Is it valuable, probably not. You can check ebay to see if anything like that is being sold under antiques, but other than that, it was not considered to be great stuff even at the time it was made.
