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.

Acman, In principle, I want your BA Mat2. However, being a computer klutz, I cannot figure out how to contact you from this website. When I click on your moniker, it takes me to a page that does not offer the possibility of sending an email. Further, JP seems also to be interested in your mat. Since he has been so patient and diligent in finding the gremlin in my TT101, perhaps I could do him a small favor in return by ceding my place in line to JP. So, you and JP can get together on that. If JP should change his mind, I do wish to acquire it. 

Of course, if my TT101 crumps again in the next few weeks, JP has to send me the mat, along with a crying towel.  (Joke alert.)
RW, I don't know about those Alibaba sources for an MN6042, but it seems to me that if you need MN6042 these days, it's a no-brainer to connect with JP and purchase his reconstruction of an MN6042 on a PCB made from discrete parts.  It outperforms the stock MN6042, and my direct experience tells me that JP will stand behind it, should you have a problem.  Moreover, having JP install it also gets you a calibration of the 3-phase motor drive in the bargain.  Obviously, I am not affiliated with JP in any way; I am just a satisfied customer.  (Sounding like a cheerleader, I know.)
Lew, thanks for correcting my faulty recollection of work on your SP-10 Mk 2.  I suspect my memory may contain some electrolytics which have faded and lost their value. ;^)

Anyway, I should go ahead with the 'lytic replacements in my Technics since as JP says, they are known to have reliability issues.
Lewm, I don't seem to have any problems with my SP-10MK III. I just thought it would be nice to have spares of the 6042 chip since so many other units use them too. I have a friend who has many SP-10MK II units that need work also.
