Yes of course. You can geht in contact with Mr. Biermann from magaudio directly.
He is a very friendly and open guy.

A turntable from 2007. Not exactly what I would consider a highly regarded turntable. There were plenty using lead back then.
One would think if lead was the thing to use one could come up with more than one example of each. In addition I would expect a more contemporaneous mention or two.
The SAT arm is out of my price range but it seems from reading that lead is a component of the counterweight and not the whole of it.
Use all of the lead you can. I do not care. If you like the sound I would not want to deprive you of it.

I was inspired by Graham tonearm which uses a lead sheet on its base. All my DIY air-bearing arms have lead sheets on their bases and lead shots as counterweights. However, extra precaution is needed if you plan to use lead on the platter and anywhere close to the cartridge. In most cases, I like brass on the platter not lead. Generally speaking, lead should be used in secondary places.
Most of the older tables use brushed aluminum
Several of the newer tables are using Glass for the platter.

VPI. My tnt v platter (on an hw19) uses lead. Probably not used anymore due to health reasons?
I guess when the talk is of DUAL tonearms this is not about making a great turntable. Just one that works and for the great majority of people that is all that is necessary. Good for them.
By the way the Walker table is not considered to be a great turntable by anyone these days.

Hey, here is a novel idea: instead of the traditional platter supported from the bottom, how about a hanging platter?
The idea goes something like this:
The platter will be a heavy mass. Use whatever material you like. Instead of a central pin over which the vinyl is placed a long rod is used. The platter mass is essentially hanging by the rod with a bearing at the upper end of the rod. Because that bearing is far away from the platter it could even be magnetically levitated, or an air bearing (but they are noisy). This creates a pendulum, however, the swing frequency will be under 1 Hertz. Damping of the the swinging motion can be achieved in various mechanical ways, above or below the platter, and should be pretty easy. The platter is driven from the top via a belt and drive system. Somehow the tonearm also must be suspended similarly, or could rest on the floor if the remaining pendulum motion is not a problem. To get the disc on and off, the platter thing must be set down and the rod detatched or unscrewed, the disc changed, and then the assembly made again and the platter lifted off of its rest. But for the ultra audiophile this might be a lovely ritual! The lifting could be achieved pretty easily using a lever at the top of the suspension rod and the whole thing would look like a tower - impressive! Perfect for the audiofile/phool crowd. Ya can't make this stuff up, folks. This could actually work well.

Ha ha, I bet you would! 😀
I'm just trying to leverage the principle that objects that hang are more stable than objects that are supported from below. And have fun. You too can try it! It's no harm to suggest an outlandish idea and get people thinking. And that is with smoking or without. FYI I can't smoke anything because of lung damage I sustained by an infection in childhood. I'm not really into any psyco-active susbstances in any form since my last coffee house visit, Amsterdam 1999.
Wandering a bit OT, the hanging idea brings up something I've always found interesting. Say you hang a turntable by bungee cords or springs of some sort. You can find the resonant frequency without knowing the mass or the spring rate. All you need to know is how far the spring stretched (deflected) when you attached the turntable. Pulled from my spreadsheet, with "inches" subbed for the cell containing the deflection in inches:
frequency=(1/(2*PI()))*SQRT(9.81/(inches*0.0254))
So, if the spring(s) deflected 3", the resonant frequency will be 1.8 Hz. It works in compression too.
frequency=(1/(2*PI()))*SQRT(9.81/(inches*0.0254))
So, if the spring(s) deflected 3", the resonant frequency will be 1.8 Hz. It works in compression too.
Is the bigger problem lateral wobble of the platter (e.g. ocurring in the plane of the disc) or vertical axis motion??? I thought it was the former.
Ya know, all this discussion and invention ideas regarding the playing of an LP record are, I have to say, kind of amusing.
Even the rediculous suggestions, but it's nice to let your mind dream and wander sometimes, eh?
Apparently, the weight of the platter itself seems to be a big topic.
And just as apparent, the heavier the better, for whatever reasons.
On the other hand, I've got a common, mass-produced turntable, not even "high end" status, yet with superior specs, reliability, and ease of use.
It actually puts current machines to shame, being 34 years old.
How many "new" platters can deliver 0.025% wow/flutter ratings?
Rumble well below audible levels.
Rock solid speed accuracy.
And all with a 2.5 pound platter!
