Hello Inmates.
I just recently acquired a Transcriptor Skeleton Turntable.
After having spent several days, enjoying the sound and also the ergonomics, I realized that something looked weird.
Closer examination revealed to me that the platter and support base (triangular) has experienced a deformation of the Tonearm base.
The Tonearm sits on a round metal sheet that is held in place to a molded base with three knurled knobs.
But the way that the round molded tonearm base connects to the base is via a rectangular section.
The rectangle has slowly over the years deformed due to gravity and now the tonearm sits at an pronounced angle.
By luck it's a unipivot Mayware and the Cartridge can also be rotated for azimuth.
I am weary of attempting to straighten the base as it may just snap off.
Also I am not sure what type of composite, plastic or material it is made of.
I will eventually disassemble it and post photos.
If this cannot be straightened, I see a few possible options.
1) Have the whole thing Laser Printed.
2) Have the whole thing CNC Milled out of lightweight Aluminum.
3) Depending on the material it is made of, have a stiff but light bracket machined and fasten from the top with screws so it pulls the sagged section up.
Anyone familiar with this vintage gem can chime in. Is this something common to these Turntables?

He claims there's supposed to be a fourth "foot" under the armboard when used with arms other than the Vestigal.
Hopefully you can either find one, or have one made.
Man, I love the archives!

Your descriptive text is good, but a clear detail photo will state the case beyond what the imagination conjures up.

I will snap some detailed photos of the issue or maybe no issue.
Will post them tomorrow morning, thanks so much for patience, a picture is worth so much more than text.

I meant to say "3D Printed",,,, not "Laser printed", duh. I have a local machine shop who are able to replicate the part for me out of a variety of materials.
Also have a local company who do 3D printing as well.
If there are any Skeleton owners out there who may be interested, I could have a few made.
To me a CNC milled part would be a major structural upgrade to what was originally used in 1973.
As long as the original Skeleton springs would properly support the delta in the weight, I may have to change the springs as well, or may have a lighter stiffer part than the original.

Here are the pics.
One of them shows the height delta between the armboard and the actual base.
The second shows the Mayware arm and the non-vertical due to the sag of the armboard.
I think that the armboard spur (that is actually part of the baseboard) has sagged.
Waddaya think?

Or maybe a possibility that this tonearm base incline is the actual design of the turntable.
This came to mind as the metal base on a Linn LP12 (not the armboard or plinth) has an ever so slight incline towards the rear and the Linn Manual cautions about messing with this.
