home recording ca.1932 EKco Radiocorder from UK

PLEASE NOTE, that sorry, this video has a number of serious flaws in the tehcnical explanations. A new video has attempted to correct the,m, and can be see at https://youtu.be/kGXqyis6j0E
This uis/was the original video description:
This ca. 1931 home recording device was, as had been all of its forbears, designed to fit onto a pre-existing gramophone.

That was OK, providing the gramophone had a motor with enough torque (= rotational strength) to turn every type of device.
Like most late 1920s home recording devices, it embossed a 'ridge & furrow' groove on a soft aluminium disc.

The one described in this video, I state that it was the first to employ the electrical system both for record & replay. This is almost certainly wrong, so I must apologise. I may have got other things wrong too, but hope you’ll overlook them as we take a quick tour of this early 1930s home sound recording device.
Best wishes,
Norman.
