Nude Turntable Project

Halcro and Gary:

In this thread (here), dgad and dgarretson suggested using springs underneath the platform that supports the tt. The thought was that one could control the frequency at which the platform moves by calculating the load on the spring. Choosing a lower freq outside the audible range will ameliorate your issue, Halcro? I have no idea how to do the calculation but this should be kinderspiel for an architect.

I haven't myself tried it, but I did something similar (I believe) when I had my sp10 on spikes resting on a sandbox which was in turn supported by 4 AT 616's (which are just fancy springs?). That set up was a great improvement over what I had before. I was going to buy the springs to test whether they could give me the same results--but for far cheaper than the 616's.

McMaster-Carr has a bunch of different springs for different loads and compression rates: here

Banquo,
Thanks but I don't have any issues that require amelioration. Also,I prefer unsuspended turntables. No springs or rubber mounts for me.

Dear Aigenga: Well the blend material I used only sees and apply as a white paint but certainly it is not a paint. I can't remember its industrial name and I don't know if even still in the market, what I know is that works great.

I respect your opinion/take on the cones but as is possible to drain some TT vibrations in the same manner transmit vibrations coming from the granite that's a resonant material, yes is heavy but to resonant. Btw, I combined the pneumatic footers with the metal cones as you can read it in my virtual system:

+++++ " Both TT's seats over three Audio Technica AT-616 neumatic suspension isolators with inverted Tip Toes ( position ) on top of these AT isolators.

Anyway, you have the whole idea.

Regards and enjoy the music,

Raul, BINGO on the damping paint. I am yet to encounter anything in the industry that works like the paint. I used it on my MARANTZ 7 STEREO CONSOLE preamp in a painstaking way. First I painted all the resistors and joints in the preamp. Next painted the chasis(three coats)and the tweaked power supply and the glass portion of the after market fuse. When people say blacker backgroung, it is a joke until you have performed this task and listen to the component in question. This preamp is a back-up unit for me but the drop in noise level in unbelievable. I will do it to my TT101 later but will first try the exercise on TT71 when it returns from Applied Fidelity. If you have a unit that you want to keep and have the schematic, go for the gusto. It works wonders on my ML Request speaker. The whole backplate of the speaker including the woofer cabinet was paint(three coats). The speaker is a different beast. Even the accompaning sub(Janis) received the same treatment but this time five coats. The only thing about the sub that vaugely resemble a Janis is the cabinet.

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.
