Audiomeca TT Replica

[Jean-Paul_2]

I will start with an Analog Front-End (1626 Darling and RESO SABA Greencone will follow: with 5Ohm Output Transformer):
- own Audiomeca TT Clone:
* DC Motor Battery Powered,
* integrated Strobe Electronic,
* Unipivot and/or Schroeder Arm (will also try to build a own wood MC),
- MC-Stage:
* Hiraga MC-Preamp Battery Powered (based on the THAT320),
- Preamp-Stage:
* TNT-Preamble, Nuvistor Dual-Mono Preamplifier, Battery Powered.

No compromise! Lundhal, Mundorf, Amplimo, no Electrolyt!

I choose the DC Motor:
- maxton A-max 32 236645 and 236647, Farnell,
- maxton F 2140 934 and 937, Schuricht.

The schematics for the DC-Motor and the Strobe Control are ready.

I will start with the Physical Design (Zuken Visula) this weekend.

I buy different exotic Woods at Ebay this weekend.

I´m braining about the Platter/Bearing and Subchassis:
- to clarify if the DC-Motor is located in the Subchassis? One or Two? the second for the DC-Motor dedicated and with the Electronic?
- 300mm Platter Diameter,
- Sandwich with Lead (will define the CG for the sandwich Platter) and an other Material, to be defined (Acrylic, Wood, Aluminium...),
- Tungsten-Carbide Balls,
- Iglidur Sleeves...

I start today with the ProE Mechanical Design (3D Volume Construction) with automatic CG Calculation.

Don´t forget, CG is also Center of Rotation CR for the Pure Mass!

Someone interrested? Open for all suggestion!

I have some fotos from the Ebay Parts. But I can´t send this Files! There are too big!!!

I decide to choose a lead free design for the platter.
But, copper is very expensive!
What kind of material can I choose for replacement?
Needs to be heavy to fix the CG in the platter.
