Additional information
The Dual CS 1257 turntable is a well-regarded automatic belt-drive turntable from the late 1970s. Here are some key points about it:
Craftsmanship: The CS-1257 is known for its high-quality construction and top-notch craftsmanship, which is evident from its appearance.
ULM Technology: It features the ULM (Ultra Low Mass) tonearm technology, which reduces the mass of the tonearm/cartridge system by 50% compared to other turntables of its time, leading to better audible contact and increased longevity.
Performance: The turntable was considered budget-friendly but still offered excellent sound quality, a hallmark of Dual products.
Maintenance: Issues such as cracked capacitors in the power supply can cause the turntable to play records backwards, but these can be replaced to restore functionality.
Replacement Parts: The Dual ULM 40 S cartridge was originally used in the CS 1257, and the recommended tracking force for this cartridge is 2.5±0.5g.
