The Pro-Ject 83g T1 Counterweight (part 156) is the genuine replacement counterweight for the 8.6" tonearm fitted to Pro-Ject T1, T1 BT, and T1 Phono SB turntables. Fitting the correct counterweight is essential for accurate tonearm setup: the counterweight must be matched to the cartridge mass so that the stylus tracking force can be set precisely, reducing groove wear and ensuring the cartridge follows the record surface correctly.
Compatibility and Use
This 83g counterweight is specific to the Pro-Ject T1 tonearm (part number 156). It slides onto the rear of the tonearm tube and is locked in place with a grub screw, allowing the tonearm to be balanced before the desired tracking force is dialled in. Refer to the Henley Audio counterweight compatibility guide or your cartridge documentation to confirm suitability for your cartridge mass.
