The Talking Machine Forum — For All Antique Phonographs & Recordings

does anyone have an image or example of what this crazy soundbox should look like when complete please ? it has a variable air gap between the rear inner face & the diaphragm.

I just found the add files feature, pics loaded of this soundbox

Now rebuilt & playing ! The diaphragm surround was advertised as being Vellum or Parchment, the Vellum version I tried was dreadful sounding but I had luck with an Impregnated silk surround that is something like the Nom-Y-Ka diaphragms made for the Astra soundboxes . This soundbox prefers simple pieces like this Piano solo. (32) Garrard -Collier soundbox for Gramophone circa 1919 - YouTube

WHICH piano solo? This one?

I've got it asking Google for the Garrard collier soundbox
The sound is certainly very good

Presumably this soundbox is the work of the same A.T.Collier who patented and manufactured the Ebonite/Vulcanite horns fitted to the Seymour Superphone and several EMG internal horn models. The horns are mentioned in "The EMG Story" but not the soundbox.
Is it a recent discovery not known to the late Frank James?

the soundbox was in parts, luckily all in the same bag & amongst a collection of workshop soundboxes in various states of completeness. These have been hidden away until late 2024 & they originally belonged to a guy who had a workshop in Liverpool

Barry Williamson?

Phono-service was the deceased business. this is the info I was given on the Garrard-Collier soundbox, it was A.T Collier that was involved.
I wonder how many of these survived ? Glad you like the video although the camera mic was pointing directly at the soundbox & picked up the needle hiss.
