Vintage DD turntables. Are we living dangerously?

Thanks for those articles rwwear....especially the one by Dave Crawley on Quartz lock where he debunks the myth of 'speed hunting' that has regularly been levelled at DD decks by its antagonists.
The TT-801 seems to be a stripped down TT-101 (without the 1 Hz step pitch control circuitry) with an added vacuum hold-down.
I have no problem with vacuum hold-down per se.....but here's where 'vintage' and 'dangerously' very much apply, as a special rubber perimeter seal is required for the platter and if this is damaged or perished....where does one obtain a new one?
Banquo has recently scored a TT-801 to partner his trusty TT-101 and hopefully he can contribute here ❓👀

I agree with the worry about the rubber which my Micro has. Although I never use the Micro, I intend to someday.

The 801 appears to have even more IC's then the 101.

Halcro:

Not quite bridge design, but google the "Bayonne Bridge roadway raising". Still the world's 4th longest single arch at nearly 100 years old, only the original arch will remain when work is completed in 2017. I visited family in Bayonne last month and was amazed to see the project even  at partial completion. 

I hope my being an SP10/Krebs upgrade owner allows me to go briefly off topic...

So that's the Bayonne Bridge...?
When I first visited NY in 1984, I was shocked to see what I thought was a copy of our famous Sydney Harbour Bridge which opened in 1932

I must say....it doesn't look as attractive with the raised roadway..🤐
And speaking about expansion of metals.....at the two bases of the arch of the SHB, there are giant steel rollers so that the arch can 'spread' due to load and expansion. Those stone pylons are purely decorative...

Halcro, I agree with you completely that the Bayonne Bridge will be less attractive with the raised deck. I spent my youth living in the shadow of the original design.  We used to jog the walkway, summer and winter, with a spectacular view of the southern tip of Manhattan.
