How to Disassemble a Dual 1249

The Dual 1249 is a turntable/record player that was manufactured in the late 1970s. The turntable plays records at two speeds: 33 1/3 and 44 revolutions per minute. The turntable's tone arm is compatible with most 1/2-inch needle cartridges. As with any turntable, taking apart the Dual 1249 gives you the ability to repair, troubleshoot and replace parts. Common parts needing repair include the platter, belt drive and record needle cartridge.

Power off the turntable and unplug its power cord from the nearest electrical socket. Remove any records still inside the turntable.

Grasp the tone arm, the long metal piece that the record needle cartridge is attached to, and lift it out of its holder. Locate the small, Phillips-head screws fastening the cartridge to the tone arm. Pull the cartridge out of its slot, and disconnect the four colour-coded wires from the connectors on the back of the needle cartridge. Remove the cartridge from the tone arm.

Remove the rubber dust cover from the platter. The dust cover is rubber mat that the record sits on. Removing the dust cover reveals the platter, which is a metal disclike plate that spins on a belt drive.

Locate the spindle, or "C" clip where the record alignment rod meets the platter. Unscrew the spindle, and lift the platter out of the turntable assembly. Removing the platter reveals the belt inside the turntable.

Grasp the belt and carefully pull until the belt is disengaged from the small lip on the belt drive assembly. Remove the belt from the turntable.

Warning

Further disassembly should be performed only by an analogue audio electronics professional.
