This is a further re-think of the R7.1.
The detail changes:
- As before the core machine is from a donor Thorens TD150. Mk1 or
- Spring suspension is retained but with fittings for adding weights next to
each spring mount. This allows ballast loading adjustments until each
spring carries the same load as the other.
- Plinth: a composite of (1-1/2 inch thick) Cherry hardwood and Baltic Birch
ply with mitered corners. Finish to compliment the Cherry.
- Motors and motor controllers. There are options to explore.
- Tonearm choices. Think about what cartridges we want to use on this
project. The tonearm must be mass-matched to the compliance of
- Will it be an Lp12 competitor / killer? Why not. Let's not
limit ourselves. We have the tech. We can build it. (
wait, wasn't that a line from an old 70's tv series...;^) )

The R7.1A plinth; We have the first build in-house! Here are
some receiving photos.
This plinth build is composed of two different wood types. Primary:
solid Cherry hardwood 1-1/2 inch thick all around. Secondary: Baltic Birch
12mm thick for the inside liner and the bottom plate.
In addition to becoming part of my private collection, this design will
become a product on offer here at The Analog Dept. I can sell as plinth
only, or I can produce a completed TD150 using parts supplied by the
buyer. More info to come.
