The Beogram 1902 replaced the Beogram 1900, and although similar in terms of styling some quite major technical revisions had been made. The most important of these concerned the motor, which had been changed from an AC induction unit to a DC servo. This new motor was not only much smaller, lighter and cooler running, it also gave accurate turntable speed regardless of mains frequency and voltage. As the motor speed was electronically regulated, there was now no need for mechanical components to change the speed, simplifying the mechanism and reducing rumble and noise. The variable speed dial was also simplified, though it remained similar in appearance. Instead of acting through a mechanical linkage, it now simply adjusted a miniature potentiometer.

The cuing mechanism for the arm was also simplified. On previous models this was visible as a large aluminium ring around the arm base, but this was no longer needed for the Beogram 1902. The revised arm was slightly lower in profile than the previous one, so it was possible to make the dust cover slightly lower too, enhancing the appearance of what was already a very sleek range of machines.

The Beogram 1902 was the top of radial Beogram range, and to set it aside from the lesser versions the platter was fitted with a damping ring around the underside of its perimeter. What difference this made is unclear, and it is doubtful how many users were even aware of it. Text copyright © Beocentral. Unauthorised reproduction prohibited.
The only disadvantage of these changes was that the transformer which used to obtain the low voltage for the motor remained energised all the time, so the turntable was never completely switched off. Because of this, it was necessary to disconnect the mains plug if the equipment was not to be used for some time. Text copyright © Beocentral. Unauthorised reproduction prohibited.
