Vintage DD turntables. Are we living dangerously?

I have just acquired a 32 year old JVC/Victor TT-101 DD turntable after having its lesser brother, the TT-81 for the last year.
This is one of the great DD designs made at a time when the giant Japanese electronics companies like Technics, Denon, JVC/Victor and Pioneer could pour millions of dollars into 'flagship' models to 'enhance' their lower range models which often sold in the millions.
Because of their complexity however.......if they are 'unobtanium'....and they often cannot be repaired.
Hi Guys. thanks. 

The tonearm was a freebie after I asked for it to be part of the deal.  Only really to be able to use the  EPC-P100C-MK4 cartridge as originally designed.   Glad I did get it now, but not being able to change any parameter of a cartridge is a strange feeling.
  I am even thinking of getting a Ortofon 320 or OMP 30/40 but not sure why as it would not sound as good as the EPC but may be a bit of fun thou.
  Any idea which one would sound better?

  Anyway in a month or so I will look at setting up my Thales tonearm on the table.

  The Exclusive P10 will now have to be sold as I have no shelf space for it.

What I find to be especially interesting about that tonearm (EPA100Mk2, according to others) is its base structure.  From the photo, it seems to be one continuous piece that broadens out to cover the entire arm board.  Is that the case, or are we looking at a separate escutcheon into which the base of the tonearm sits?  If it's all one piece, that would provide a nice "sink" for energy generated in the arm wand. Reminds me a bit of the modern Durand Telos (big money), but I would bet that if it were possible to do a head to head, the Technics would be superior.
Thanks for those Links JP....
That arm is a serious piece of work 👁
Good score Shane 👏
very interesting the brochure, on the internet I had never found anything about it.

the arm collects the best EPA 100 and 500 but I believe it is limited to a narrow range of cartridges.
The TP4 cartridges have never reached the great quality and musicality of the traditional MM and MC cartridges and it is for this reason that it is limiting in choice, that you have supplied is a very good cartridge but
your turntable deserves the best for the cartridges.
