The Pro-Ject 73g Counterweight (part number 016) is a genuine replacement counterweight for a range of Pro-Ject tonearms. Correct counterweight selection is essential to achieving accurate tracking force: a counterweight matched to the cartridge mass places the balance point closer to the tonearm bearing, allowing precise stylus force adjustment and reducing unwanted mechanical resonance.
Compatibility
Pro-Ject supplies a comprehensive range of replacement counterweights, each identified by a part number, to cover the wide variety of cartridges available. Selecting the correct weight for your cartridge ensures the counterweight sits at a mid-point on the tonearm stub rather than towards the extreme rear, which is the optimal position for balanced, precise tracking.
Installation
The counterweight threads directly onto the rear stub of compatible Pro-Ject tonearms. Once fitted, the tonearm is balanced by rotating the counterweight until the arm floats level, after which the tracking force scale or a stylus force gauge is used to dial in the precise downforce recommended by the cartridge manufacturer.
