Is that power supply really a 1984 vintage?
I'm not a graduated archeologist like Jean Luc Picard, but during my expeditions in historic circuits I've never seen e.g. these transformers with the yellow tape around in anything before mid-90's. Also that black shiny 1 µF cap does not look much before 2000 to me.
Maybe I was cut off from this timeline, by just not getting the real hot stuff as in my experience 80's equipment was copper-iron-brick-style and baking tray-style heat sinks - black anodized, rarely blank - with TO-3 graveyards.
I'd appreciate any input, even to prove me wrong, as long as I get explicite pictures with it.
