You will have to adjust the tonearm's counterweight. Set it according to the requirement of your cartridge/needle. Check the suggested weight in the manual of the carts/needle.
Sir, are you referring to this:
Tracking force range - 1,6-2,0g (16-20 mN)
Tracking force, recommended - 1,8 g (18 mN)
Tracking angle - 20°
The currently installed one, ortofon f150, counterweight is set at number 2. so i have to manually adjust it at 1.8? i do not have a gauge and have not adjusted it since i bought it from Sir Augmentum here in pdvd.
Thanks again!
