Vintage DD turntables. Are we living dangerously?

Vent holes on say the bottom plate likely will do little since
there's no where for the heat to exit on the way up.

So an open bottom is the best I can do, even though the plinth
depth leaves none of the can exposed.

Halcro, Continuum is dead. Long live Dohmann. Apparently, Mark Dohmann, one of the principles of Continuum, is now producing a tt on his own, for about $36,000 with a Schroeder LT tonearm, a relative bargain compared to the Caliburn. He is said to have developed the new tt in collaboration with several others with various types of expertise relevant to the project. But this is not a DD, nor is it vintage.

Yes, definitely provide some ventilation for a TT101.

Lew, At RMAF I heard two Dohmann TT set-ups, both among the better analog presentations at the show. Dohmann incorporates a Minus K spring-based vibration platform into the plinth. A friend of mine has had great results with the Minus K with another TT. Perhaps it's worth pursuing.

Lewm,
I know the whole sordid Continuum story directly from Mark.
He is an astute audio guy with a genuine love and passion for the possibilities.
He has always appreciated the damage that structure-borne feedback causes to most turntable-based systems and has been an admirer of Minus K platforms for many years.
He is in fact the Australian Importer and Distributor for Minus K so it is no surprise to see him develop a turntable with a Minus K 'built-in'...
Somewhat reinventing Linn...👹❓
And let's gets real.....no-one is going to reinvent a new DD turntable which can be built in a 'garage'.
HW did it with a cogless super motor that still can't match the performance of the 30 year old Victors and can't be made for less than $30,000...😱
Rockport came the closest with its Sirius III but it would cost $200,000 today and was somewhat let down by its tangential tonearm....

And yes....ventilation AND breathing space is a crucial requirement for most vintage DDs....but especially the Victors.

That Schroeder arm is NOT an LT model. The headshell offset angle and the lack of extra pivot point at the base gave away that it is not a pivoting tangential or Linear Tracking tonearm.

The Schroeder arm appears to be a carbon fiber version of the discontinued Artemis Labs TL-1 tonearm.
