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.

@lewm Here is the SAEC manual in English if you can read it.
and another page. Someone just posted it online, so i can share his images here, hope it’s ok.

He said that drilling and screwing it’s for wet playback technique, wow

READ HERE
I certainly owe Raul an apology for doubting him.
Raul, I apologize. Wherever you are.
SAEC also do not recommend to use record weight (disc stabilizer) on top of the disc according to the manual as it will reduce the effectiveness of the solid mat. So we did everything wrong :))
