ABSTRACT:
A pick-up arm assembly for a record player comprises a pick-up arm mounting, a counterbalance device which includes a counterweight and which is mounted to the pick-up arm mounting so as to be pivotable about vertical and horizontal axes, and a pick-up arm comprising a tube having sound pick-up means disposed at one end and an insert fitting means disposed at the other end. The insert fitting means is capable of being received by the counterbalance device to enable the pick-up arm to be removably fitted to the counterbalance device. The counterweight is mounted in the counterbalance device so that it is substantially horizontally displaceable with respect to the horizontal pivot axis, and adjusting means is arranged at the end of the pick-up arm remote from the sound pick-up means to enable substantially horizontal displacement of the counterweight to be effected when the insert fitting means is fitted to the counterbalance device.
