Nude Turntable Project
The problem I see with the post connection is if anyone has fooled with them in the past the leverage from the post will have a tendency to move the eyelet on the other side if done without caution. I would unwrap then rewrap with less turns and resolder eyelet on backside and solder the wire. If you translate that link you would see the ones with solder are suppose to be the repair. |
Halcro, 09-12-13: HalcroThe Final in the picture is missing most of the TT. It is a VTT1 Platter & bearing with non standard Lead Console plinth, and a Pioneer DC motor drive. It is missing the original SPZ plinth and it is also missing the original sine & cosine wave regenerated power supply and original motor. Here's an early Final VTT1 with the SPZ plinth. http://www.hifido.co.jp/KWfinal/G0301/E/0-10/C09-43580-46106-00/ In my VTT1 the wine/cosine generator is separate from the motor and uses a separate power amplifier for providing motor drive. The Takai/Final Labs preceded both the Melcos and the big micro's by 7-8 years. The Melco's are interesting - they use embedded titanium in the bearing assembly, and the thrust pad is mounted on a spring designed specifically to the platter mass. The platter uses the Okubo mass formula to obtain equilibrium and minimise bearing "friction". The Takai/Final Labs have an inverted bearing, placing the platter centre of gravity well below the bearing point, whereas the Melcos/Micro use the conventional bearing. The Takai/Final Labs also use sine/cosine wave generated power supplies for the AC motors. The Melco's & Micro's are less sophisticated in this area. |
Is no one interested in the magnetic fields concentrated at the normal arc of the cartridge? It would be helpful and interesting if someone with a smartphone would install the Tesla app and repeat my experiment. Is this a problem? Does it effect all DD turntables? I have ordered mu-metal sheets to try and redirect the magnetism away from this area. More on that in a week or so. Gary |
