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.
TT-101
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 malfunction.....parts are 'unobtanium'....and they often cannot be repaired.

@pbnaudio Thank you for your offer, we could write in private but I'm not able to make the most of this forum I can try to search in some way your mail :)
Well, I foolishly purchased a broken Dual 701 off of eBay Friday. I'll put it in the stack of projects to modify. That is, if I can get it working?
For those of us who are not Dual cognoscenti, what is a Dual 701?  I guess we should assume it's DD.  Dual pioneered the coreless motor.  In fact, most coreless TT motors in use even up to today (Brinkmann) are naught but developments on the Dual motor.  Does the 701 contain such a coreless motor?
