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.

@lohanimal  haha, that's what i already posted, but the author of the blog and people who helped him are all well known audiogon members :) So you're already on the best source of information here on audiogon.   
I believe this is the second time that someone has cited that article in Audiocircle only to be reminded that all the principles are right here on this thread.  I am the guy who gave Thuchan (aka Eckart) the chip for his TT101.  I gave him two, in fact, because up to that time I had no idea whether the ones I bought from Hong Kong would actually work. (They look correct, but who knew???)  Sadly, I do not have an inexhaustible supply, and I prefer to keep a few for my own TT101.  However, the good news is that you too can purchase the chip from Hong Kong.  I think the part number is "SC3042A", but do not take my word for it; the part number is engraved on the black surface of the top of the chip.  If you need one, search for that part on Alibaba, and you will soon have so many offers to sell that you won't know what vendor to choose.  I chose the one who had the best command of English.  Those vendors never give up.  Even 5 years or so later I still get emails from some of them. By the way, my TT101 did not need a new regulator chip. It's still running on the original.

By the way, there are several other chips in the TT101.  I don't know what they do.
