My sister has a very old system, compromising of modern Bush speakers (actually sound as good as a typical £50 Richers pair with a very clean sound nothing like mini system speakers) a Pioneer SA520 and a Cambridge Audio CD32. The amp was given to me years ago I just wondered what a modern eqv would be. I would say compared to my Camrbridge A640 it sounds a bit commercial like it is trying too hard but for free it sounds pretty damn well amazing. Also how old is this amp? I am guessing late 70's early 80's but I can't tell.
