Description

Inspired by Jean Nantais. If it wasn't for the Lenco thread on Audiogon my L78 which was given to me by a friend may have never been resurrected from the garage or worse - given/ thrown away. The horror! Many thanks to Jean for his enthusiasm and generosity in sharing his knowledge along with Vinyl Engine and Arthur Salvatore who must be one of the deepest thinkers in audio.

The base material is 19mm StructaFlor (chipboard bonded with stong waterproof resins that make it very stiff and dense) and 4mm hardboard. The central layer is 6mm Alucobond (aluminium/resin composite).

Alternate layers are screwed together which made it a lot easier to fabricate. The armboards are Karri hardwood which is very dense and blunt tools in no time. Almost the entire underside of the turntable has been damped with a lead doped vinyl sheet and neoprene. Most moving parts have also had some form of damping material bonded to them.

The original design was to accommodate only two arms but having ordered the mg-1 air bearing arm from lin it has been modified to fit the arm at the back of the plinth.

There is also a filtered i.e.c. socket routed into the plinth at the back so i can experiment with leads.

The Base will be a similar composite layer construction with an air bag and alucobond damping layers

My goodness, gracious, me! (read with an africa accent)

This is like - I don't know what man! Weo!

Just shows you how good an old Lenco is and you went the right way to damp the chassis - that is a Lenco's biggest problem. But your's is sorted now!

Congrats!

NB - Now you need one of my balsa-tone arms that I developed for my Lenco L75. Effective mass is +/- 4grams.
