Meltrope Pick-Up Arm with Four Independent Adjustments
It requires more than a cursory examination of this pick-up arm to assess its full value, since the many adjustments provided are cleverly camouflaged in the clean lines of the design. Closer inspection reveals, however, that four independent adjustments are provided. The main arm is built up in two parts, the longer being a hollow sleeve which telescopes over a short rod and permits an adjustment of about 2in. in the overall length. Its height above the turntable can also be varied by loosening a small grub screw, which secures the arm to the vertical pivot pin.
The pick-up carrier is pivoted on the main arm and can be fixed at any angle in relation to it, a knurled nut on the underside of the seating serving to lock this when the required angle has been determined. Two spring-loaded plungers enable the pressure of the needle on the record to be varied. This adjustment is made by means of two grub screws on the underside of the pivot and located in the centre of the large, knurled nut.
A spring clip on the main arm, and another on the top of the main pivot support serve to position the flex leads and prevent them from becoming entangled in the pick-up or turntable and its controls. Heavily nickel-plated brass is used throughout.
Each carton contains an instructional card on which is explained the importance of correct alignment. A cardboard protractor is included by the aid of which the error at any part of the needle travel can be determined. Clear instructions are given regarding its use and the steps to take to reduce the error to the smallest possible value. The price is 17s. 6d.
