The Pro-Ject 49g Counterweight (part number 014) is a precision-machined replacement and upgrade counterweight for Pro-Ject tonearms. Correct tonearm tracking weight is fundamental to faithful record playback, and selecting the right counterweight ensures the stylus can be set to the manufacturer's recommended vertical tracking force with accuracy and stability.
Precision Balancing
Weighing 49 grams, this counterweight is designed to balance tonearms fitted with medium to high-compliance cartridges. It threads directly onto the rear stub of compatible Pro-Ject tonearm tubes, allowing fine vertical tracking force adjustment via the graduated ring. Machined from solid brass, the counterweight offers high mass density in a compact form, which is beneficial for tonearm resonance control.
Compatibility
The 014 counterweight is compatible with a range of Pro-Ject tonearms including the 8.6, 9cc, 10cc, and various variants of these arms. It is also used as original equipment on several Pro-Ject turntable packages. Always verify the counterweight thread specification and stub diameter against your specific tonearm before ordering.
