OK.
I'd still like a phone, such as the BeoCom 750 or BeoCom 1000.
Speakers I'd of course say the BeoVox 2500 or (and) the BeoVox 5000, as they represent the novelty of B&O at the time.
Television I'd still say the same.
As for system, I don't really like the early 80's stuff; I much prefer the BeoMaster 2000/6000 or maybe the 4000.
The Grand Prix 610 is a nice old radio!
