Indulging a little more on the Vintage Japanese theme
Here’s a family photo of two Fidelity Research tonearms, the FR-12 and FR64S, together with the Kenwood L-07D tonearm.
The latter is the tonearm from the legendary Kenwood L-07D direct drive turntable (with after-market Orsonic headshell).
You can see from the close-ups below that the Kenwood is an engineering work of art, showing what the resources of a larger high-end manufacturer can achieve.
The Kenwood arm weighs just over 2.5kg! Note the precision instrument-type vernier geared helicoid arm height (VTA) adjuster wheel with its huge, collet-chuck type lever locking mechanism. Yup, that wheel mechanism says ‘0.1mm/revolution’. The underside view is breath-taking (in a audio-geeky sort of way, right?). The arm tube is, they say, composite 3-layer of aluminium with carbon fibre & boron laminated over. Sadly, my sample does not have its original resonance-reducing, carbon-boron laminated headshell… okay I think you’re beginning to get the picture.
Oooh… that’s enough hifi porn for a day.
