Sending you schematic on how to change from AC to DC.

Thanks Rugyboogie (RB)
Pani, RB, Maril others. I have been preparing my room and my listening for two OTL amps arriving within two weeks. Once I have settled into the sound will hookup to battery and will I also scrounge around for a cassette tape.

Pls try when you can the small wood blocks under the plinth. Three small blocks next to the existing feet. It takes a few seconds to insert them and remove. Interested in your impressions.
Cheers

Ct, I did try using a block of Ebony wood next to the TT feet, high enough just to raise it off the feet. It added a small dose agility to the sound but also took away a bit of the flow. Additionally the tonality of the wood also came through. I removed the wood.

Hi Pani. That is what I heard too plus less blackness. I am personally ok with a little more agility, but not at the expense of the flow (rhythm) of the music.
Cheers

There is a development. I tried a nylon fishing line string instead of the silk thread and there has been a very significant improvement in pitch definition and timing and also in dynamics. Try it, it is cheap and super effective. Possibly it will tell you what I was pointing at in my first post in this thread.

Pani,
What gauge fishing line did you use. Any particular brand or type?

Hi Pani – is the line you are using one of these.

The fishing hobby has similarities to our audio hobby ?

Maril55, my fishing line says .28mm diameter (nylon). Here is the one I bought:

Ct0517, I know some people use the monofilament fishing line also and they supposedly great. I wanted to keep it simple so I tried a nylon fishing line of super strong variety and not very thick.

Guys please try this out. It costs nothing but could be an ear opener for sure.

Thank you Pani,
That line is not braided, is it?
How soft is the line, comparing to the silk thread?
Another idea- Walker Audio recommend 2-4 mm silk belt for their Proscenium Black Diamond TT, they supply the belt with the TT
I'll contact Lloyd Walker, who happens to be a member of out local Audiophile club, with some questions
Best

Maril555, yes you are right, it is not braided. It is quite a bit harder than the silk thread but still soft ennough to be used a string. Can you not borrow Mr.Walker's belt to try out ?

I'll talk to Walker and I see, if I can try it

I use braided fishing line, non teflon, 10 pound weight with the original motor mounted close to the tt. Big improvement over silk thread, available at Wal Mart. Also I use a motorcycle battery along with a small battery charger available at Sears. I insert a 10-15 volt dc to dc converter in the line to the motor. This regulates the voltage at exactly 12 volts dc with a varience of .02 volts until the battery voltage drops to 10 volts, model PST-1212-8 available from Powerstream Lund, 801-764-9060. I believe this was about $100. I use the optional hardeded ball just barley touching with a Redpoint 4 pound weight on top of the record. The table is mounted on 3 Boston carbon blocks elevated off the springs. The improvement was like listening to a different tt.

Marty t,
when using the battery- did you convert the motor to DC first? And how exactly did you do that?
I'm looking at battery power for my Verdier, as well.
Do you know by any chance, waht is the record weight, that is featured on many Verdier pictures websites- looks similar to yours- tall SS cylinder with some LED lights at the bottom?
I have Micro Seiki ST-10 weight, but it doesn't fit the Verdier spindle, which is larger diameter, than my Technics Sp-10

Marty_t
In addition to what Maril555 said; is there a reason you chose to add a converter to the audio chain, rather than just bypass the converter in the Verdier motor itself ? Sorry if I misunderstood your post.

Here is another thread that I feel is worthwhile to try out and it is free.

If you call them they will send you some samples of a few sizes. A few yards of each size in packages like this.
Kevlar/Aramid

Hi Pani
Re: my fishing hobby comment earlier.

As someone who sport fishes in the summer I find similarities between that hobby and this Verdier. With fishing the line will vary as it is based on the type of rod/reel at one end, the line itself, the lure at the other end; the target game, water conditions and performance that you want. Thinner lines cast farther, are more transparent – to humans anyway - have more sensitivity but are not as durable.

The Verdier similarly allows us to tweak the sound by changing the line/thread between the motor and platter system. The difference in threads is significant in my room more so than any belt changes I have done with previous TT’s. I also listen in nearfield.

For me there is a similarity to interconnects, and speaker cables that we use between our components. While some audiophiles have difficulty grasping how interconnects/speaker cables can change the sound. With a TT once it is understood that its all mechanical and we are dealing with resonances / vibrations - I feel its much easier to understand.

So I have maybe ½ dozen fishing lines in the house. I tried some Trilene XT for fun again.
Ultra Low Vis Green, .30mm Diameter, 8lb test

In my system it brought the vocals a little more forward. A little more revealing (dynamic) similar to the Kevlar. At first it was nice and different, but after 3 or 4 lps I noticed a tad more noise than the silk and a smaller / condensed soundstage. I will look for some smaller diameter 4 lb test and try it. I have an area near the Verdier where I just hang past tied threads. IMO - If someone was a little OCD you can could probably identify which threads work best with which lps (as they are all engineered differently) and use different threads.

Do you guys ever worry about catching the stylus when putting the new thread on?

Cheers

Ct, could you try reel tape ?

Maril555
I removed the motor cover revieling the motor and circuit board, then I spliced into the wires coming out of the AC to DC converter and just before the circuit board. This enables you to still use the speed adjustment knobes.

I don't know what weight uses the led lights. My weight is 4 lbs, available fron Redpoint.

Ct0517
I use a DC to DC converter to regulate the voltage. As battery voltage drops the speed changes, the DC to DC converter maintains 12 VDC within .02 volts from 15 VDC to 10 VDC. The Verdier regulation is not as accurate.

Thanks for the thread info.

Pani
Ct, could you try reel tape ?

Pani – I tried to do this with reel tape for you but was not successful.

My Vintage Granito is one of the old ones. It did not come with a setup ball, or a switch on the back of the motor for belt versus linen options. It was designed to run only with thread or a thin line.

I did tie some tape together but even at the lowest motor speed setting, the platter is running way to fast. Thats when I looked for the switch and found none. lol. I have seen them in new manual pics. So no listening test, sorry.

I did find something out though that you and the others may find interesting.

I have mentioned that with thread the inertia and braking in place allows the platter to spin for about 30 seconds when the motor is shut off in my room. When I tried this with the reel tape even though it was not optimized and spinning way faster than 33 1/3 – the platter spun a little over half the time (18-19 seconds) when the motor was turned off.

This tells me that I really affected the original inertia / braking design that Mr. Verdier built into the platter behavior to deal with lps. Imo - with tape the platter's magnet braking and increased friction becomes dominant. No longer an equal marriage with the motor.

Cheers

Thanks for the clarification Marty_t

Hello Marty_t,
I believe the record weight you are referring to may be the Sutherland Timeline Strobe.

That's a weight, I was referring to

Here is Maril555's link.

Is it the first pic Maril555 ?

Ct,
Yes, it is. Do you know what that weight is?

Maril555 it looks like a custom center weight.

from Gerald Wurz's System

http://www.galibierdesign.com/systems_gerald_wurz.html

scroll to the bottom.

This is probably a Gyrascope

http://www.lys-electronique.com/GYR33GB.html

Thekong- you are right, looks exactly like Gyroscope.
Do you know who sells it, and how much $$$?
Ct
That's the same Gyroscope in Wurz's system

You tube "LYS Gyroscope" for a slightly different style.

Let me ask an original question differently:
Wouldn't it make a significant difference, to use a high quality motor controller, such as Walker Precision controller for instance, with stock Verdier motor. Would it be a better performing option, than a battery driven Verdier motor?

Maril555,

Let's take that one more step. Does a market exist for a truly high-end controller/motor/belt combination that would fit a variety of belt drive turntables?

Hi Mosin,

I, for one, would be very interested to have a truly high-end controller for my belt drive turntables!

But then, do you have an estimation on the cost?

Isnt Motor controller like the Walker meant mainly for AC motors which cog ?

Mosin,

Yes, I think a market exists for such a product. However, for it to be truly universal (working across a variety of synchronous motors at different frequencies and possibly voltages) would require a huge effort. If one were to include adjustment of all the various parameters involved in proper motor control, the effort would be Herculean. To market such a product, and provide adequate support for it would be the embodiment of madness. In my opinion, such a product cannot by its nature be turnkey in operation, and would require an end user of sufficient technical capabilities. A nightmare waiting to happen in my opinion.

Thekong,
I can pull it off, but I'm not sure I want to. It would be very expensive, but very good. At least, I believe it would. I wouldn't hazard a guess as the exact price because everything I do seems to make its way into the stratosphere these days. I may build one just for kicks to see how it works outside my comfort zone. IE: other turntables besides mine. Who knows?

Palasr,
I realize that, so I believe the only way for it to happen would be if the maker included the motor, too. It would have to be outboard. Some choices would need to be limited, and that's one for certain. Otherwise, it is like you say, Herculean.

Hi Mosin – something a little different maybe - outside the box. is this even possible ?

I'd like an ultra high end controller only. You're not allowed to touch the manufacturer's motors. A controller that has the balls to handle the Jean Nantais Lenco; then when I clap my hands it switches its functions to handle the Verdier requirements which are at the other end of the scale; Clap a third time and it becomes a line conditioner for the DD SP10.

I can only play one turntable at a time, and they are in different rooms so it needs to be portable too.

Remember this is a wish list item. Is this too much to ask for ? Even possible electronically? I can make the clapping part optional if it helps. Will settle for a three way switch.

I agree with Palasr' post.

Palasr
Embodiment of madness

imo - this can describe this hobby very well at times.

Ct0517,
Unfortunately, the requirements for various motors is so vastly different that a one-size-fits-all solution is beyond the realm of possibility. Any controller with that claim would be a hoax. In the best case, it wouldn't be a very elegant solution.

Mosin.
Have always tried to teach my kids to think big.
Tried to follow some of my own advice.
thanks for popping my bubble on the idea...
Cheers

Live and learn...
I understand, that Walker controller would do little, if anything for Verdier motor, which is essentially a DC motor, and Walker is intended for AC variety.
Now, is there a controller, that would improve on Verdier built-in controller, and better yet, can be run by a battery?
Mosin,
it seems, that challenges of building an "universal" motor controller will be enormous, but how about making it more specific? To build one, that's intended for DC motors only? (little selfish, isn't it?)

Mosin,
reading your original question again, I do think, that there is a market for a stand alone controller/motor/belt combination. And why wouldn't it be?
One could use this package with ANY belt driven TT, right? Did I get your question correctly?
And a controller in this case shouldn't need to be overly complicated, since it will be designed to be used with a specific motor, that will be a part of the package.
it's not going to be compatible with ALL belt drive TTs, due to the diiferences in platter mass, the height of the chassis and platter, etc., but still...

Pani, I just noticed your thread. You may have moved on from the idea of a Teres DC motor drive pod, but I got over your "problem" by neatly drilling the --unseen-- back of my turntable base to accommodate the Teres speed reader and never looked back. I am in the middle of transferring this set-up to a recently acquired Granito (Auditorium 23 version from Germany) based Platine Verdier. I discovered today I need a ball for the bearing! I have found the Teres unit with mylar tape drive on my Townshend Rock (heavy plaster of Paris base, vertical sided Delrin platter) to be an exceptional performer. The Motor is a very important part of the chain. I discovered this when upgrading from Teres' already very good "Signature II" motor, to a pre-used (now discontinued) Teres "Reference". I was quite amazed by the lift in results with the still better spec'd motor, with precious metals in certain places etc. Music was delivered with still more commanding grip, bass impact, air and space. A good quality well driven DC motor, with the relative inelasticity of a mylar tape drive, on a suitably isolated table delivers wonderful music with great impact. In my case, with a Triplanar arm, Decca SC4E cartridge, Croft valve pre, Yamamoto A-06-3 SET, and "Loth X Troubadour" single driver horn loudspeakers. I am looking forward to final set up of my Verdier. Do you think I'll like it ? cheers.
