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.

It starts immediately and runs at exact speed without hesitation at the push of a button - just as it should".

Is it possible to explain further how this is accomplished and also post some pictures to help a layman like me to fully understand what you have done.
Thanks Aigenga..........I knew the looks would not be to everyone's taste....and initially scared me somewhat :-0
But now I think the covered 'guts' look stodgy in comparison.
As Ecir said above.......I think it looks "wicked" :-)

I really admire the way you have supported your TT-101 on the wall-hung shelf....and its interesting to read about your use of the central 4th spike?
I remembered well your 'damping' of the outer metal casing and following your advice, I bought 2 bungy straps on Ebay and wrapped them around the outer casing....without however hearing any differences?
It was your reported improvements in damping the outer casing which encouraged me to remove it completely :-)
And the improvements have indeed been audible....but how much is due to the removal of the casing or the better supporting steel cradle or the decoupling of the deck from the cradle support....I don't really know?
Halcro, I am happy for any (if any) role I played in inspiring your creativity. In our crazy hobby, everything matters and often it is impossible to figure out what does what to our precious sound.

Audpulse, Sorry but no pics available on this one. Here is my best info:
1. first why do you want to adjust the thrust plate - is there a problem with how the platter turns? If not then sit back and think about it some more.

2. if you want to go forward keep this in mind: the pressure on the plate is not random, not at all - if you get it wrong the platter either won't turn or it might make it harder for the table to get a grip and get spinning. Which I think might have happened to me.

3. The TT101 has a center screw that is easily visible and accessible from underneath once you remove the bottom can. To do this it is critical that you first remove the platter, then turn the tt upside down onto a bowl that is broad enough to sit stably as you work.

4. The center screw provides the pressure on the thrust plate. It is screwed in to an exact spot - don't forget that. It is also sealed with Loctite or some such sealer which you will need to scrape away and replace when you replace the screw.

5. Once you take out the screw you should replace the oil in the well - about 1/2 ounce will do. I suggest synthetic motor oil. You can wipe it out with a clean cloth. Careful in that there is a loose ball bearing sitting there and you don't want to lose that.

6. Reassembly is just that, but don't forget to seal that screw or your oil will leak out.

I hope that is useful to you. Questions?
