Terrific! I did read that recent article but admittedly, had long since lost interest in my Three Muses soundbox. With its Frusto-Conical Re-entrant Diaphragm indeed - good grief - presumably also vitified with fortamins.poodling around wrote: Thu Jul 31, 2025 3:57 amVery interesting indeed.chunnybh wrote: Thu Jul 31, 2025 12:02 amWell Christopher Proudfoot answers that question in the latest FTR. His article on the "Frusto-Conical Re-entrant Diaphragm" mentions it was patented by a Mr. Cottons who also patented the use of "whalebone stylus bar springs" which were use on The Three Muses' Tremusa soundbox.Do those dished inserts and their square "washers" seem to be made of some kind of fibrous and/or resinous substance?
Now just that is worth a years subscription of FTR.
Thank you Christopher!
This information is also mentioned in the October 1978 copy of the Hillandale News 104:
' The Tremusa (also found as the ‘Three Muses’, produced by Repeating
Gamophones Ltd., of Bond St.) is, like the Barcrole, of solid aluminium construction; it has a composition
diaphragm, and the stylus-bar is held in tension by two flat springs of whalebone'.
