It's all potentially very good gear. Mac supports everything they've made and Audio Classics in Binghamton is also ready to help. The MR80 is a nice tuner.
The Maggie MGIII are also nice speakers, and can definitely be serviced by the company if needed. I've heard of delamination issues with the voice coil.
Soundsmith does service Tandberg, and if you're into cassette tape, it's an excellent deck. I would take that over a Nak.
The oracle is likely a safe bet, and the AR gear, well, that's a crap shoot with old caps lurking within. Could be fine, but certainly, given the vintage, recapping will get you likely at least another 20 (or with modern caps, perhaps more like 30 years) out of the gear.
Nothing wrong with that- some folks still love shooting with their 1950's or 1960's vintage M3's
