Nude Turntable Project

There were no bad parts, just bad connections. I ended up resoldering all the feed thru eyelets, then flipping the board and removing the solder with a sucker, then resoldering them with much less solder. They all look pretty clean now. I know other companies that used the eyelet method had reliability problems. For some reason the solder cracks around the eyelets, probably related to different coefficients of thermal expansion.

That's from an email my tech Dave Brown sent me. In a different email, he distinguishes between what he calls 'feed thru eyelet' boards and 'plated thru' ones. The Victor evidently uses the former. I am completely ignorant of the meanings of the 2 terms--am just passing on others' wisdom as I received it.

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.

Very informative. Thanks again.

Banquo363, you beat me to it. BTW thanks for the report of trying your table without the tin can.

And here is the equally famous Takai Lab Final VTT-1 belt-drive turntable similar to Dover's.....although he has the Parthenon model I seem to recall which is quite different to this one?

The 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.

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.
