I did check the Nakamichi out, If, like you, I had one restored everything working, I would work hard to get the best out of it.
however, I would not choose the Nakamichi Dragon CT, and I might politely say no thank you if someone offered to give me one.
this listing has links to the oem brochure and owners manual
there, I found the arm height is not adjustable, they originally supplied a kit of shims, and you need to carefully measure your cartridge height, and use the proper combination of shims as per their chart pg 8. I detest shims!!!!!
And previously I posted an excerpt from a review I read
"I have to be perfectly honest with you, I find my Yamaha GT-2000 better sounding, even after the centre search."
Keep in mind, I want easy use of alternate cartridges, either two arms on a larger plinth like the Luxman PD444, JVC PL-2 two arm plinth, a custom plinth,
or changeable arm wands on a compact unit like the Technics SP15 or 10 in their base with dust cover. It's a shame they don't offer that solution for a new SL-1300G
I'm not a fan of a separate glass platter that slides around on a sub platter, it moves too readily in this video (my instincts, solve a problem but introduce a different problem)

and I find the Technics EPA-B500 tonearm base changable armtube side mounted sliding slot far more precise auto-alignment than a round tube with a round locking ring.

I have never actually seen or heard a GT-2000, and never see a photo of one with two tonearms. That might be worth doing.
