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.

Are you saying that you may replace the motor of a TT 101 with that from a TT81?

Yeeees.... but only  if it were exactly the same!

Whilst the dimensions of the enclosing cage are identical.....to think that the TT-81 is in any way 'identical' to the TT-101 is a mistake...👅

Halcro, As I recall there were back and forth arguments as to whether the TT81, like the TT101, had a coreless motor.  I thought that question was finally answered in the affirmative.  If so, are you saying that the coreless motor in the TT81 is not identical to the one used in the TT101?  Because, if the motors are idenical, I would guess that it is the electronics that differentiate the two, most of all, and it is not inconceivable that a motor from a TT81 could be incorporated into a TT101, resulting in a feaux TT101.  Which I think is the question here.

Lewm, whilst the TT-81 has the identical positive and negative speed control in the servo detector......it does not have the coreless motor of the TT-101.
