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.

Tim, Being a Connecticutian (a term of my own concoction) by birth and still a Connecticut Yankee at heart, I know Willimantic quite well. A prostitute could starve there, unless she also liked to babysit or cut grass.

As it turns out, I am wrong about the association between the word "hooker" and General Fighting Joe Hooker, even though he was notorious for his patronizing of prostitutes. Seems the slang may pre-date the civil war, back to the early 19th century New York or even to England in the 1500s. No one knows for sure.

Halcro, Could you be induced to make me one of those? How much does it weigh? I ask because if I were to modify your design in any way it would only be to maybe add another "ring" so as to enhance mass.

Now, as to the ferrous nature of the outer cage, that is interesting and it suggests to me either that Victor chose it as a matter of convenience or that it was indeed chosen for its shielding effect. Yes, I would like to know Al's opinion also, but being ferrous it would be a shield of sorts. Note that in the owners manual also they make a big point of connecting that ground lug on the outer cage to audio system ground. That WOULD be essential if it is functional as an RFI or EMI shield. How are you grounding the TT101 with no cage? With my balanced Atma-sphere phono stage, tt grounds have always been irrelevant. With my single-ended outboard phono, grounding is critical.
Dear Nikola,
Big spikes are necessary to counter the large deflection of my cantilevered shelf :-)
I grabbed the slotted metal surround screen and held a magnet against it………..
This screen was magnetic steel!

Strange for a TT that is marketed with the word laboratory ?

Just kidding Henry – cool looking project. Looks like you are having a lot of fun.

I like Banquo’s use of the word “steampunk aesthetic” which if what we were looking at was all analog stuff would work for me. I have stared at too many digital circuit boards so I would be inclined to want to keep it under covers myself. From what I have heard about parts availability for that JVC I would want to prevent a setup that could cause an accident pulling of some wire ?

My recommendation holds to put the table and the armpods on a dedicated shelf supported by decouplers – the AT616’s come to mind. Even though you are on the wall already.....

Now I realize you are in beta trial mode and the setup is being tweaked but is that an old Canadian penny shimming the left armpod ? :^)

Cheers
Lewm,
Did you not remember my 'incident' when I had the ground cable connected to one of the Halcro amps (as it wasn't long enough to reach the preamp?
After placing the Victor on the copper Fidelity Research Cu-180 platter mat to test 'isolation'.......when I turned on the power....I blew up the Halcro phono stage and also the Dyna XV-1s cartridge which was connected at the time.
A very expensive exercise.....

Since then I have not had the ground wire connected (my previous TT-81 did not even have one)......and all three arms use fully balanced XLR interconnects.
Nice work Ecir,
You're close to being a fully-fledged member of the 'Copernican Club'?
What material is that surrounding your Victor (is it a TT-71 or 81?)?.
It's really neat....but how do you manage with ventilation?
And those arm-pods are impressive.
Are they bronze?
How long till you're able to 'play'?
