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.

Mind you, the Littman was preferred by cardiologists, not audiophiles. As I recall, it was quite good for picking up murmurs. But another virtue if you are schlepping it around a hospital all day is that it is very small and light compared to some others that have complex and heavy bells. (The bell is the business end of the scope.)

Lewm, I am mostly playing my high compliance mm carts at this time and the UA7045 is not compatible. I think the 7045 is excellent and would recommend it and by extension the 12" 7082. Also Jim Howard did an excellent job on the EPA100 so it really sings, so I really enjoy it.

I am interested why you think the vibrating transformer is not effecting the oh so sensitive stylus? It seems to me that I need to quiet it anyway I can.

A soldier has his uniform, an officer my have a sward, the English lawyers have a wig and a doctor has the stethoscope. This is called 'non verbal communication' but
somehow it seems to work. Such that Ataturk wanted to raise his country into the Western civilisation by ordering that every Turk was obligatory to wear a hat. According to
the same logic the only thing one need to do is buy a stethoscope.Ie a hat will not do anymore.

I finally do understand why you are concerned about the mechanical vibration of your transformer. A good platter mat can isolate the LP from such low level disturbance. Also, sometimes you can make mechanical transformer hum go away by judicious tightening of the bolts that hold the transformer laminations in place. You have to do this very carefully (don't just crank down on them with all your might) and symmetrically (tighten all of the usual four bolts a little at a time and see at each step whether the hum is reduced or finally gone).

Can you hear the hum with the bell of your stethoscope placed against the platter mat, where the LP sits? If not, no worries.
