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.

Dear Audpulse: Good to hear it.

Even that in many ways my Denons are near the Victor designs and I could think that performs " similar " I just bought ( ebay. ) a Victor QL-7 TT ( mint condition. ).
I did it not because the TT but because the Victor tonearm ( that I want to try it. ) that happens that in this TT model is the Victor high-end 5045 ( similar to the 7045 . ) that Victor marketed as a separate/stand alone tonearm.
The last time I saw a 7045 tonearm was over 750.00 and I paid for the Victor TT/5045 400.00!!!! and that TT comes with a " especial " TT71 version that through its specs/numbers even or surpass the TT101 as is with the S/N ratio that in the QL7 is 78db against the 75db in the TT101. Speed deviation figure is the same as the drift characteristic and in theory use the same platter:

This measures does not surprise me because something similar happened in the Denons where the top DP-80 measures 78db and its " little " brother DP-75 has an spec: 80dbs.

I think I was and am lucky to found out this Victor combo at that price in mint condition, the seller told me that he thought the unit is new!

Years ago, happened something similar: I was looking for a FR FR-64 and suddenly I saw it on ebay as part of a Luxman PD-310 TT that I was unaware how good was it ( Now I know it is very good BD TT. ), that way I bought the FR tonearm I was looking for where I had a high reward through the Luxman TT.

I don't know where but I think I have a little amount of that " magic " blended paint that as you I will use it in the QL7.

Regards and enjoy the music,

In thinking about coating the motor I remembered that the TT-101 motor runs hot and needs to vent. I can feel the heat in the TT body after a couple of hours. Just something to keep on mind.

Gary,
I'm sure you're right about damping the 'cage' and I intend to do so if....and after....I have eliminated the 'source' of the feedback?
Incidentally....I tried the 'bungee cord' treatment to no effect :-(
My thoughts are....that even if I dampen the 'cage' successfully WITHOUT treating the cause.....there is still transference of energy which is manifesting itself in some ways?
Banquo,
I agree with Gary. I don't want a suspended (bouncy) table.
With the Victors supported on the outer cage......it is very easy to induce 'movement' if the supports are not executed correctly? And that 'movement' is magnified enormously because of the lever-arm of the metal cover in relation to its connection with the platter.
I've experimented with rubber and insulating materials and whilst the bass may seem to improve.....the highs are badly affected?
Evidently, I didn't express myself clearly, but let me try again.

The springs don't go directly beneath the turntable cage but rather below whatever platform the tt sits on, in my case a sandbox. The weight of the tt + platform results in the spring having a certain frequency at which it moves. My sandbox and tt weighed around 150 lbs and there was certainly no bounciness to the system. I take it no one believes one can turn a non-suspended table to a suspended one by changing the type of platform the tt rests on. Or am I missing something?

At any rate, Halcro, you mentioned an issue with low frequencies affecting the tt-101 and I thought this might be worth a shot, since it theoretically at least allows one control over just that.

But if one is like Gary and you "don't have any issues that require amelioration" then I'm truly envious :).
What is the cage made of? I always thought that if I could find one of these tables to play with that it might be a good idea to have a disc cut out of plate, .125" to .250", of the same material that the chosen pod material is to attach to the bottom of the cage. This should fix the flimsy section that the feet are attached too and should help sink any resonance.
