EDISON BELL MAGNETIC PICK UP CONVERSION, 1930's

Wireless was becoming more popular in the early 30's; mechanical gramophones had been around for much longer.

If the acoustic head of a Gramophone was removed and the round block with a pillar for a needle in this kit was mounted in its place, then plugged into the other section which had a 4 pin valve plug on it, the unit could be plugged into the socket on a wireless receiver that was reserved for the valve prior to the speaker valve. This would connect the new electrical pick up to the audio output stage of the receiver, thus using it as an amplifier.
