Vintage DD turntables. Are we living dangerously?

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...

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. 

Just finished an evening of listening to my SP10 MK2 back from Krebs upgrade by Bill Thallman. Also added a new PBN Audio power supply and the TTWeights carbon fibre/kevlar/cork mat. Focus and resolution have very much improved. The difference is not subtle. The mat plus TTWeights heavyweight brass/aluminum collet clamp weight close to the stock mat. Well worth the cost. 

I will listen for improvements as I run in the Krebs mods, lewm. I will post my impressions in a month or so. One of the things one gets with the Krebs mod is, in essence, a servicing of a 30+ year-old motor. Additionally, the worn bearing thrust plate is replaced. I had caps replaced by Dave Cawley when I purchased my table from a UK seller 5 years ago, and Bill has now replaced those that Dave didn't. So I have serviced pretty much what can be, and I consider this essential maintenance for the table. Add in a fresh gloss black automotive painting of the deck to match a new plinth, and I have the table looking as good as it plays.

Hi Peter,

I decided to buy the Micro Seiko CU-180 Replica mat you referenced a few weeks ago. I'll let you know how it sounds once it arrives.

Hi Peter,

I received the CU-180 clone platter mat. It fits the SP-10 MK2 platter and damps ringing very, very well. I'm keeping my TTWeights carbon fiber/kevlar/cork mat atop it, as both mats are not too thick (6mm together) and sound a bit better than either alone. What I notice most is how resolving and textured the music is at modest volume.  

I've not turned it into a MK3 platter, but I am most happy with the result.  Thanks again for posting the link a few weeks back!

In case anyone seeks to upgrade their direct-drive turntable plinth isolation feet, I have used the Delrin version of these for the past 2 years and am very satisfied:

Replacement neoprene "O" rings can also be had on Ebay, as they do dry out and crack/split over the years. The "O" rings are the feets' contact surface with the shelf upon which the TT sits. The cones are hidden from view by the 2 piece design.

For reference, my table is a Technics SP-10 Mk2, "Krebs upgraded" (by Bill Thalmann, who also did some preventive maintenance parts replacements on the board and added a nice orange strobe LED - Bill does great work), with a PBN Audio outboard power supply. The TT and feet are in this plinth:

The workmanship of the feet is impeccable.
