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: Where did you connect the third "ground" wire from your IEC plug to the chassis?

With your ultra transparent casing you should be able to see what I am referring to pretty easily. The main circuit boards are stacked using hexagonal brass rods that screw together and screw into the chassis. I unscrewed one right near the small circuit board where the pc connects, removed the small lock washer at the base of the rod where it screws into the chassis and put my tinned and flattened green wire into that space, and tightened it down.
Easily done.

Shane,

I don't believe that it's a rubber mat under the Jico leather mat in that image...?
It looks to be more like a rigid plastic mat like the Achromat...?
I have friends who like to use a leather/suede mat on top of a rigid one (especially metal) like the Cu180...in combination, the two mats can often ameliorate any stringency in the upper harmonics...
I really can't imagine using a leather mat on a ribbed rubber one...but hey....you can certainly try it...๐Ÿ˜œ

Gary,
My problem with changing the power cord on the Victor is.....where do I stopโ“๐Ÿ‘€
The TT-101 plugs into a 240v to 100v step-down transformer which itself plugs into a PS Audio Power Regenerator which itself plugs into the mains.
Do I need to change all three (two of which are hard-wired)โ“๐Ÿ˜ซ

Henry, Yes.
You are an audiophile and a diy guru.
You started this trend and opened our eyes, so why stop. lol

Over time the bonding can loosen and the damping rubber ring will come lose, without this material the platter is better suited to announce the second coming.

Thanks for the tip, totem395. Upon inspection, the adhesive securing some parts of my rubber ring had indeed dried out. I couldn't tell just by looking; I had to peel back the outer rim of the rubber (the adhesive is applied in square blocks roughly midway inbetween).

Readers of this thread will know that my victor experienced a resurrection, but now that my ring is secured, I have perhaps put in abeyance the second coming?
More to discover
