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.

Lew, Now you tell me. The greatest cowboy hero of all time told me to eat lead. He missed me cause I was partially behind a tree, but I gave it a try. Can't say I liked it much. Didn't have a lot of taste, and caused tremors of the spirit and insomnia.

Now that I think about it casting should be relatively easy. 

I thought Walker has a giant lead platter?  Lurne' figured out the "ideal" platter which is 8mm lead sandwiched between black methacrylate. Black whole grain isn't gluten free, but once those tremors overtake, you become one with the universe and it matters not. The 8mm thickness in our miniverse is based on the reflection back of any vibration when it hits a boundary. Since we only have 6mm ......  You just need a different adhesive, 

Regards,

Yes, So far as I know as told to me by Lloyd Walker himself, the platter of the Proscenium is one giant slab of lead.

From a 6 Moons Review of the Walker...
The base is crushed marble in a lead and epoxy resin and gorgeous. The Platter is 75 lbs. of encapsulated lead, the most resonance-free material known to man.
It also used to be on Walker's website but I see that he has since removed all reference to lead.....👀

More nonsense from the marketing gurus of a typical audio company - materials do not have resonance, they have bulk properties which affect the resonance of the structure in which they are used.
In the case of the Walker the composition, materials used ( including epoxies and any other materials ) and the manufacturing process itself will all affect the final resonant properties.

The question remains, what is "encapsulating" the lead platter of the Proscenium?  Possibly Walker now plays down the lead platter for fear of either having violated some environmental regulation or for fear of being singled out on that same basis.  Given that the Proscenium turntable now retails for over $100,000, the platters are not likely to end up in some toxic waste dump, not until Armageddon, anyway.
