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.

As Lew said... Thuchan has just completed his preliminary set-up and listening sessions with his re-built TT-101

Audio16 is his own Weblog where you can see his current amazing system components.
His initial set-up is similar to my initial beginnings

but he is having a slate cradle made to match my granite one

I look forward to him also writing a few words here about his vintage DD experiences....because he has had quite a few 👏

PS Lew, note the Copernican isolated armpod setup that doesn't seem to trouble Thuchan 👀❓

Totem, Please do keep us posted.

"What I don’t get is whether the guy who figured this out"
"he seems to infer that his circuit is actually more accurate than the original chip, although I don’t know whether one needs to worry about a few Hz when the frequencies in question are in the millions of Hz"

If you had "digested the thread thoroughly" as you claimed, you would have understood that jpjones has comprehensively researched and measured both the original circuit and components and has carefully measured and tested his new board at every stage of development. You are wrong to claim that he "seems to infer that his circuit is actually more accurate". Jpjones provides test results and scope data that support the published results. This provision of test data is a breath of fresh air compared to the faith based changes touted by others in this thread who provide no test data and furthermore argue that test data is not needed to support their claims.

Dover.
You are quite correct. I do not provide any objective proof that the number of servo error corrections have been reduced by my upgrade. However since I know what the upgrade process entails, it is reasonable to conclude that this is indeed true.
It is surprising that you, as a doctor, prefer to support unsubstantiated claims whilst trivialising others who have provided extensive test data that support their observations and claims.
