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.
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 are 'unobtanium'....and they often cannot be repaired.
I'll leave this to JP or someone else with more expertise, but I have to wonder whether using a power conditioner and not per se a step-down transformer could have anything to do with causing the hum that you perceive.  Obviously, yours is a standard 100V unit.

In the longer term, you would want to replace ALL the other electrolytics, as well as those on the Power Supply board.


Are you certain the Elgar unit is working correctly?  I see that it's advertised as having sine output.  I'd try a simple step-down as a sanity-check, à la

According to the literature the transformer in the 101 is a potted toroid.  If that's vibrating, something is VERY wrong.


Tried a new step-down transformer. It is now 98% hum free. A BIG improvement over the Elgar. Which confirms I have a broken Elgar. With ear pressed against the platter mat, I am still able to detect a difference between on/off.

Would other TT-101 owners check this with their units if they can detect any difference between on and off?

Thank you.
