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.

Wow, what a great thread. However, no mention so far that Goldmund and Micro-Seiki
used JVC core motors.
Anyone care to elaborate on this?
Wahwah, I recently found out that the Luxman PD-444 (made by Micro-Seiki) used a slotless/coreless motor. So MS apparently used both?

Lewm, I thought some more about it and tried a new test: I lowered the stylus directly on the Achromat platter mat, at zero rpm of course, then I raised the volume to twice my listening level and I couldn't hear the transformer humming in my speakers. So, 'if it ain't broke, don't fix it' seems to hold here. I am leaving well enough alone.

A little stethoscope is a dangerous thing, because it imparts a little knowledge.
I don't dare buy a stethoscope for fear of feeding the neurosis. What if I heard some noise from underneath the platter? I wouldn't be able to sleep until I eradicated it.
