Vintage DD turntables. Are we living dangerously?

Hi Halcro. The bottom cover on the JVC is rather flimsy. I owned QL7 and QL-A7 before so I know they are not very rigid. I noticed you placed 3 footers right below that bottom cover. I know you like the nude style and no-plinth approach. Would it be better to have maybe some cylindrical footers, literally almost foot long, that support the chassis where the motor is directly mounted on? This way it can still qualified as "nude" and you eliminate that wobbly sheet metal and adds rigidity. Might be worth a try. I sold all my QL-7s so I can't experiment anymore. But I would like to know what you think.

I am a JVC fan but I came to the conclusion that I only like the ones that use coreless motor and QL-7 and QL-8 use core motor but the 101 is coreless and it's their top of the line and I am salivating here.... I would love to hear it compare to, say, a Kenwood L-07D, another coreless masterpiece.

Have fun!

Yes you are !

You're right Hiho about the flimsy bottom cover to both the TT-81 and TT-101 and when I tried to support the TT on the three spikes positioned inboard of the edges.......the table was able to be rocked by grabbing the outer edges and twisting.
However when I moved the cones so that their centerlines coincided with the centreline of the vertical edge of the cover (in other words.....the cones half protruded from the bottom edge)......I could induce no movement whatsoever. No wracking, no twisting......utter stability :^)
I think both you and Lew are correct about the advantages of core-less motors which both the TT-81 and TT-101 share.
The interesting thing was that the 81 and 101 share everything in terms of construction, motor, platter etc and the only ostensible difference is in speed detection and correction with the TT-101 having double bi-directional monitoring and correction.
When I slid the 101 into the same place as the 81..... The difference in sound was astonishing?
If you click my 'Systems' page you can read a treatise I posted there by Peter Moncreif who maintains that accurate instantaneous speed control is the fundamental role of the TT.
So it would be interesting to know what the speed detection and correction abilities of the Kenwood and the SP10 are? Perhaps that's where the heavy platter and high torque motor of the Technics come to the fore?

It does seem odd that the owner of a business that thrives on selling used gear would make the statements about dd attributed to him by Henry or Henry's source. Based on the results of my Google search, those Denon chips seem to be available all over Hong Kong, if he would stick his head out of his door. C'est la vie.

This is what I was alluding to in the synth world- its a bid, based on fear, for a higher price- maybe for the cost of repair (replacing an 'expensive' chip that you don't have to replace, but get to make money on), being unwilling to admit to not being able to repair the unit, that sort of thing.

Bottom line is chip failure is the least of your concerns! They literally will be the least likely thing to fail.

Thanks Lewm. MY SP10s are rebuilt by Bill and at the time he informed me that the chips were also used in thousands of less expensive tables. I have no reason to doubt him and I've never seen a table this easy to live with that also outperforms anything else I've come across. I expect to pass my MKllls on to my children(assuming they want them).
