Notice That There Are Not Many Survivors of the MC from the early 19080's or so?

@neonknight 

don't need it, OK,

but to be clear, both the ones I just posted are LOMC,

as is mine, it's Van Den Hul on Sapphire Tube, 0.26mv output. Mine is Talisman S; not an Alchemist, a review

This Hardness chart indicates Boron is harder than Sapphire, however, a Sapphire TUBE might be stiffer than a Boron ROD. Nobody is making tubes these days.

Note: Beryllium, and Beryllium Tube are not on the chart. I have read this about it:

"Other high-tech features of the V15VxMR include an ultra-thin (0.0005!9) beryllium Microwall/Be cantilever, patented MASAR polished stylus, and the Side Guard stylus-protection system. According to Shure, the 6.25 stiffness-to-mass ratio of the new cantilever is the highest of any cantilever ever made, and results in outstanding high-frequency tracking. The low-mass Micro-Ridge stylus shape features a very small tracing radius, which reduces distortion; and the MASAR polishing of the contact area results in an ultrasmooth contact surface".

Most here are intelligent enough to recognize an attempt at humor...but apparently some are not. 

@theophile The operative word in that sentence...attempt. 

There used to be a gentleman here that managed to ferret out many a vintage moving coil. Been a few years since he was active here...forget his moniker. Hope he is well.
