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.

Richard, What interests me most is WHY did you decide to make an entirely new platter for the Mk3?  And what are the consequences to how it works associated with incorporating one half of a speed sensor device into the platter?  (What's a "toothed magnet"?  I've never been bitten by a magnet.) Did this entail a basic change in the circuitry?

There were several reasons for the new platter...

- I had just sold my Goldmund Studio and admired the design of its platter, which is acrylic and lead. Although not the lead plug inserts it used. My design uses a lead disc insert.

- The SP platter audibly rings a little without a mat.

- Cosmetically the SP platter looked weird on my newly build triangular plinth.

- It was a fun challenge making a completely new one.

This was some 25 years ago and I cannot recall the performance differences between the two designs, but I did stay with the new assembly. I still have the original platter and it would be possible to try it again. Have heard the original perform exceptionally well with some of the more exotic mats available.

The magnetic teeth are there on the standard platter, so the electronic architecture is original.  Check out the small diameter central ring on the underside, be careful you don't get bitten.


 


cheers.  

Perhaps you are  like me; as I have aged, I am less and less inclined to DIY or Do-It-MYself, except when it comes to the actual electronics.  I still enjoy messing about in a tube circuit. I look at the 3 slate plinths I had made for Lenco, Denon DP80, and SP10 Mk3 (slate + wood in this latter case), and I wonder where I got the patience and energy.  I would not take on such projects again.

I think that we slow a little as we age, less youthful bravado.

I have built/rebuilt  virtually all of my system but, like you, I would not have the energy to start again.

I spend most of my time listening, which is after all what the system is for.


cheers.
