Servicing Dual 704, 721 Counterweight (2x Anti Resonator)

Great video! 1.5 hours of hard work. The original spring was still ok, I just had to bend it quite a bit (sweating!!!) without breaking it. But then everything worked out. You just have to take a lot of time.
Thank you very much, without this video I wouldn't have dared to do it 🙂 (Dual 721)

Hey mate I have a dual 704 and was wondering if the gimbal is meant to be a bit loose and wobbly like that ?

[@seraphin_creates]

hiya :)
the gimbal should not be too loose or too tight. adjusted with the friction of the bearings: < 0.07 mN vertically and < 0.15 mN horizontally, if i understand the service manual correctly. if you adjust them to have no slack and make sure the contact points are clean you should be in relatively good shape i think.
have a look for yourself here: www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwia06iY5K_uAhVsi8MKHaDVD8kQFjAAegQIBBAC&url=https%3A%2F%2Fwww.vintageshifi.com%2Frepertoire-pdf%2Fpdf%2Ftelecharge.php%3Fpdf%3DDual-704-Service-Manual.pdf&usg=AOvVaw1Xsxdo-JadaZnUv1xQmksY
