Nude Turntable Project


I could not fit the whole story in this Forum so have had to add it to my System Page.
I am attempting to hear if a 'naked' DD turntable can sound as good as Raul claims.

Banquo, to handle the tt I remove the platter and turn it upside down on a large flat bowl that is covered with a dish towel. The washers are about 5/8" in diameter and 3/32" thick. They will raise your platter a tad by raising the entire motor. That gives you more leeway as to how tight that bearing thrust plate screw must be. Not tightening it too much is rather critical for clearance as well as proper alignment of the motor components.

Lewm, the 1/16" neoprene bonded to 1/32" steel do not make for a spongy mount especially if they are torqued down. Your point is quite valid but my ears tell me this is better. Psychoacoustics no doubt but c'est la vie. Anyway the washers that JVC used, being two metals and thin are a pain in the ass. As Banquo found out (and I did too) they tend to get lost in the machine.

Naked.....not 'nude'!
5 months after mentioning my idea to Banquo.....about designing a 'cradle' out of stainless steel flats to 'drop' the TT-101 into......I finally got off my bum and did it.
Designing is one thing......but drawing it and then finding people to quote and then waiting for the thing to be built....is quite another :-(
The cradle is made from 4mm engineering Grade 316 stainless steel all laser cut and welded.
I had thought to simply drop the whole TT in together with its flimsy black steel bottom perforated cover......but then I thought......why not go fully naked and avoid any possible resonances related to the cover panel?
The result will not be to everyone's taste.....but to me it's more in line with my thoughts on the Copernican view of turntables whereby the tonearm pods are now correctly visually dominant surrounding the skeletal structure of the turntable.
I suspect that someone like Lewm will find some way to interpret this 'cradle' as some kind of 'plinth'.......but what can I do? :-)

How does it sound?
A bit too early to file a report......but it is audibly changed.
For the better of worse?.........stay tuned.....
the exposed guts and criss crossing of various metals evokes a steampunk aesthetic for me. very cool Halcro. Looking forward to your impressions of the sound.
wow Halcro, you really did it! the naked guy - a very courageous approach. How did you put the table on the frame - any rubber or softening parts in between?
what do you think about a Japanese paper wall around the skeleton, still looking through but no dust entering the electronics?
Thanks Banquo,
Will report in due course.
It takes many records, arms and cartridges.....not to mention different listening sessions......to be convinced of what one is hearing?
