Hi: 

My Dad remembers a high end audio player from the 70s or 80s that he thinks was b&o. He described it as like a dart board cupboard. You would press a button and then speakers would fold out like cupboard doors. I can't see this as being possible. I am assuming given the age that a record player would be the main source but could this be loaded vertically?

This could after all, just be a mirage!
