The KB NRP11 is a 3 transistor player which is fitted with a Garrard BA1 battery record deck, designed to play 7 inch singles at 45RPM.
The cartridge is a Cosmocord GP69 crystal pick-up with a Cosmocord SK2 stylus.
The whole unit is powered by a single 7.5 volt battery such as the Ever Ready AD42, and the speed of the player is adjusted with a 100 ohm potentiometer so that as the battery voltage runs down the speed can be adjusted.
There should be a printed Stroboscope disk on the turntable to aid setting the speed accurately.
The player switches on as the pickup arm is moved toward the record.
