Electrical pick-up GPU No 2 |
| In brown painted metal box with two
binding posts for the connecting wires at the top. A needle
can be inserted in the needle holder below. |
 |
| By replacing the acoustic reproducer
of a gramophone by this magnetic pick-up and connecting
it to a radio or amplifier, greater amplification was
possible. |
| Brown supplied a free adaptor plug
that made it possible to use the electrical pick-up,
without altering the wiring of a radio or amplifier. |
| Brown also claimed
that needle scratch could be reduced considerably, but
that was mainly because this kind of early sound boxes
produced little treble and because the signal-to-noise
ratio in the manufacture of records had improved with
the introduction of the electric cutter. |
| Brown introduced this product in
November 1928. |
Adaptor plug |
| The original price of the pick-up was 23 shilling. |
