The Pro-Ject Counterweight Debut Pro S (140g) is a genuine replacement counterweight (Pro-Ject part number 1940875159) designed specifically for the Pro-Ject Debut Pro S turntable. Setting the correct tracking force is fundamental to good analogue playback, and a correctly matched counterweight ensures the tonearm balances precisely, allowing accurate and repeatable stylus force adjustment without unnecessary stress on your cartridge or vinyl.
Designed for the Debut Pro S Tonearm
The Debut Pro S is fitted with a 10" S-Shape aluminium tonearm with an effective length of 254mm, mounted into a precision-milled bearing housing and equipped with an SME-type headshell connector for cartridge switching. The counterweight mounts to the rear stub of this tonearm and is adjusted to achieve a balanced null-point before the tracking force dial is set. This 140g counterweight is the correct mass to balance cartridges in the weight range compatible with the Debut Pro S, including the factory-fitted Pro-Ject Pick-IT S2 C moving-magnet cartridge.
Genuine Pro-Ject Accessory
As an official Pro-Ject part supplied through Henley Audio, this counterweight is manufactured to the same specification as the original fitted to the turntable. It is the correct choice when replacing a worn or damaged counterweight, or when setting up the turntable with a cartridge that requires a different mass balance to achieve the recommended tracking force within the adjustment range of the tonearm. For cartridges outside the typical Pick-IT S2 C weight range, consult the Pro-Ject Counterweight Chart at Henley Audio to confirm 140g is the correct option for your specific cartridge.
Simple Installation
The counterweight slides onto the rear stub of the tonearm and is secured by friction — no tools are required for fitting. Once installed, balance the tonearm to the horizontal null point, then rotate the tracking force dial to the cartridge manufacturer's recommended value.
