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.

I do not like "switching" power supplies, switchnig are good for playstation or others commercial products, I have a feeling that they inject more spurious than quality, but mine are just ideas not substantiated by concrete facts.

If the engineers of Matsushita have decided for this type of power will have their good reasons, I do not think it’s just for greater material savings = greater gain .... in hi-end products is not tolerated to reason to economize.

If we analyze other examples, Linn in 1998 put on the market the CD 12 top-of-the-line player, which cost thousands and thousand of dollars and had "switching" power supply inside; in 2018 Naim produces separate power supplies with traditional components to make up-grading of its products from the cost even in these cases of thousands of dollars.

Every IHMO manufacturer has its own thinking on how to make the power supplies .... buyers should think only to hear and understand if improvements over old machines are audible instead of worrying about the technical performances.
I think we've had this discussion of switching PSs before on this thread, but maybe not.  Anyway, at that time I also pointed out that David Berning, the designer of Berning amplification products, has been using switching power supplies at least in his (tube) amplifiers for many years, certainly more than a decade.  Meantime, his products are much admired and not inexpensive.  So far as I know, no reviewer or end user has ever complained about switching noise or anything of that sort.  I have used (briefly) two of his ZH270 amplifiers in mono configuration to drive my Sound Lab speakers and detected no problem related to PSs.  Keep in mind that DB is a brilliant fellow and an innovative engineer; not all switching power supplies are created equal. So-called linear power supplies can also be crappy if badly implemented.
Dear @best-groove:  """  If the engineers of Matsushita have decided for this type of power will have their good reasons, I do not think it’s just for greater material savings...."""

agree with you and agree with @lewm too and additional makes no sense that a good switching power supply design can introduce any kind of " distortion " when the cartridge signal never and can't pass trhough it.

Yes, we are talking of Matushita group !.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Just get a belt driven SME Model 20. It sounds better than any of these. And it's built better.
So surprised to learn here that you love SME turntables, Invictus.  Not. Will the SME 20 also take out my appendix?  Can I go to it for advice on investments?  Does it do dishes?  I figured your posting here on a belt-drive turntable must be your idea of a joke, so I hope you can take a joke, too.
