As can be seen from the photos it has suffered damage to the anti skate mechanism. There is nothing to retain the anti skate adjustment knob/spring/spindle. I can see a small recess machined in to the end of the adjustment knob and also on the inside of the tonearm pivot bracket (bearing).
Does anyone know if there is supposed to be a small circlip or the like to retain this assembly? The manual doesn't show any such detail as it only furnishes the tonearm as a complete unit.
Any help appreciated, thank you.
