Lenco turntable (Part II)

Great thing about bank holiday weekends is that you have more time to work on your projects! At least I had this time round.

After doing the initial calibration to the Lenco idler mechanism, I got the turntable finally assembled on the new plinth. It runs very quiet and smoothly despite having not dampened the idler wheeler  as recommended in the Lenco Heaven forum. I need to look into it but so far the turntable runs really quiet.

The arm board is a bit lower than it needs to probably. I can adjust the VTA with the micrometer but I should look at raising it to allow the arm to be rotated to the right for best placement. The micrometer is preventing this to happen. Will refine later.

Ok, impressions so far after all this work then. I did many upgrades this time to my system so it is hard to quantify which part contributed the most to the sound improvement. Overall tone and clarity has improved. I suppose that the heavy plinth makes a big difference to the bass clarity. The overall tone improvement and detail is quite likely to be the Audiomods tone arm as well as using the Clearaudio Virtuoso Wood MM cartridge that Tony kindly give me to try.

A rare occasion in my hi-fi life is too see me switching from electronics to basic mechanics. I’m not either good with woodworking or mechanics :). Either way, the GL75 rebuild is coming along quite fast. I sealed the original arm holes in the top plate and painted it yesterday. Today, I spent all morning waxing the plinth. The afternoon was devoted to rebuilding the Lenco turntable mechanism and testing the re-lubed motor and spindle. I still need to do further calibration, but so far so good.

Here are some pictures of the building steps:

Lenco GL75 plinth

Last week I received a fantastic job made by Carl for my Lenco turntable project. A lovely plinth designed to fit a Lenco GL75 top plate and a Rega-like arm mounted on a hardwood tone arm board. The plinth is made to order and Carl made a very neat work as you can see on the pictures.
