There are many different types of sound-boxes. Ideally the one for your gramophone should be the original one with the same logo as the gramophone itself, however it is often necessary to find a replacement sound-box or to upgrade the one you have.
There are two main types of sound-box, the standard one as found on most UK machines in which the end of the tone-arm plugs into the sound-box (Type 1) and the “Continental” type in which a tube at the back of the sound-box plugs into the end of the tone-arm which has an enlarged spring end to accept it. (Type 2)
In the picture type 1 is on the left and type 2 on the right
