J.B.WOODROFFE ELECTRIC GRAMOPHONE PICK UP, 1930's

In the 1920's Electric recording was a possibility, the general public were using clockwork Gramophones to play 78 rpm records using acoustic pick ups, as Wireless sets were becoming popular it could be possible if your Wireless had a Gram input on the rear of the set to plug in an Electric pick up similar to one of these. J.B.Woodroffe patented this particular type in 1927 although many similar types were to follow, this was one of the first. It consists of a horseshoe magnet with a moveable armature attached to a standard needle, which fits into the bottom of the unit with a small knurled screw, the coils pick up the movement, and produce a variable current which is amplified by the wireless speaker amplifier.
