I have a Philips amp/receiver whose age I don't know but I think it's from the 70's or possibly 80's. I still use it for music and sometimes films or series when I don't want to use headphones. The connected speakers are probably also from the same era. I can't confirm the age of either since the amp is from my late father and the speakers from some past neighbour.
